Undefined function or method '...' for input arguments of type 'double'.

2.084 visualizzazioni (ultimi 30 giorni)
I'm getting the following error when I try to run some function m-files: ??? Undefined function or method '[name of function]' for input arguments of type 'double'.
I know this usually happens when the file isn't in the working directory, but that's not the case here.
When I was running these m-files in a different directory on my computer, it worked fine. I moved them to another directory on my laptop, and they're still fine, but I get this error on two of my desktops.
Thank you.

It sometimes gives you this error if you don't have the right toolboxes installed for the certain function.
If a particular function is causing an error. Try typing
help functionName
If this results in like a certain toolbox is required for this function to work. Just click on the hyperlink or underlined link which is given in the terminal.
It will direct you to the appropriate package. Make sure you save any programs. Since installing the packages requires MATLAB to restart.
Cheers !!

I am pretty sure that the reason why this problem happened is because of the license of the toolbox (package) in which this function belongs in. Write
which functionName
and see what will be the result. If it returns path of the function and the comment
"Has no license available",
then the problem is related to the license. That means, license of the package is not set correctly. Mostly it happens if the package (toolbox) of this function is added later, i.e., after installation of the original `matlab`. Please check and solve the license issue, then it will work fine.

In my case, there was a function that is used in my code but it was not in the directory, so by changing the location of the sub function and copying in the active directory , the problem is solved now.

That's not the problem. The file is in the working directory.
I've tried running it from the editor, but I'm getting the same error.

Hi,
Please consider that you should be EXACTLY in the same directory; and not even in sub-directories within the right path.
I hope this solves the case. It worked for me.

I've encountered this error when attempting to call MEX functions that were built/compiled on machines running a different version of Windows.
e.g. I build a MEX file from source code on a 32 bit machine, transfer it somewhere down the road to a 64 bit machine, and then attempt to call the function.
Seems like this error often has little to do with the arg type being 'double.'

Seems like this error often has little to do with the arg type being 'double.'
Well, sometimes it genuinely is an issue of the arg type, as shown here
>> sin('a')
Undefined function 'sin' for input arguments of type 'char'.
Clear 'sin' does exist, but just doesn't know what to do with char input.
As for the MEX-file issue, that has nothing to do with the 64bit-ness of Windows, only the 64bitness of the MATLAB version. 64-bit MATLAB will be looking for files with extension 'mexw64' whereas a 32-bit compiled mex file will have extension 'mexw32'. So, that really is a case of MATLAB not being able to find a matching file.

For me,the reason why this error occured was because I used a method that actually did not belongs to the object I used to invoke.This means that I should first transform my object to another type of data,for me,I actually have to change the object belongs to vehicle class to mini class to specify its data type. OOP's philosophy is indeed very important for you to understand why it occured and solve the error.

Mathworks does not define a function named "wavelet" in any toolbox.
I checked and it does not appear that any of the File Exchange contributions happen to define a function with that name either.
You appear to be using the code from G08isu.pdf. It appears to use software from colorado.edu; it looks like you can find the source code at http://paos.colorado.edu/research/wavelets/software.html

I met the problem ??? Undefined function or method 'cdfcalc' for input arguments of type 'double'. Besides, when I use cmd "which cdfcalc", returned that no such a function found. I wonder if I missed to install something?
Plus: When I went to the download page, I have these to download: Installer.exe MATLAB77.zip Communications_Toolbox42.zip Signal_Processing_Blockset68.zip Signal_Processing_Toolbox610.zip
I downloaded them all and installed. But when installing, it alerted me that no Simulink. How should I handle this?
  1 Commento

Walter Roberson il 11 Ott 2016
cdfcalc is from the Statistics and Machine Learning toolbox. It appears that you have not installed that.
The Signal Processing Blockset that are trying to install requires Simulink and is useless without Simulink. It does not affect use of the Signal Processing Toolbox by itself, so you should only install Signal Processing Blockset if you install Simulink.
If you have a Student Suite license, then you might simply have not told the installer to install those packages.

I have the same problem.Here is my error.
An UndefinedFunction error was thrown on the workers for 'configurePin'. This might be because the file containing 'configurePin' is not accessible on the workers. Use addAttachedFiles(pool, files) to specify the required files to be attached. See the documentation for 'parallel.Pool/addAttachedFiles' for more details.
Caused by: Error using parallel_function>make_general_channel/channel_general (line 929) Undefined function 'configurePin' for input arguments of type 'double'.

matplot2() appears to be a function in the R programming language.

As the getsnapshot documentation clearly states, its input must be a video input object. Your error message tells us that you are not giving getsnapshot a video image object, but a numeric value. You need to give it the right kind of input (the one that the documentation tell you that it requires).

Error:Undefined function ‘execute’ for input arguments of type ‘double’.
raspberry pi simulink
Causes
Actually this can happened by many problems, one of them could be, the Simulink Support Package files didn’t downloaded correctly and may be there are missing file, and to be sure of that write:
which functionName
for example which execute
and see what will be the result. If it returns the comment “Has no license available” or just gives error , then follow the below soution and if returns with path and a name of the file ,then restart your matlab and check ,if not solved it could be another problem.
solution
Download all the package again, but before doing it, you have to remove SupportPackages folder in the following path: C:\Users\your_pc_ userrname\Downloads\MathWorks and start downloading the package ,it will works and mathworks will download the all the rquired files in that path for size not less that 716MB
i just restarted my pc and matlab and every thing works well ,thanks to these maklab team people http://www.maklabacademy.com/error-simulink-support-package-raspberry-pi-hardware-2016-2017/

If you're trying to run the example from this blog post, you will need to download this File Exchange submission. I recommend using the Add-Ons manager to add it to your MATLAB installation (search for "deep learning 10 lines") or you can download it and manually put it in a directory on your path.
Note that the requirements state this requires Image Processing Toolbox and Neural Network Toolbox, so make sure you have those products installed.

That is a utility / helper function in Bioinformatics Toolbox. Check the output of the ver function to determine if you have that toolbox installed.

Could you confirm that

If so then try

if it starts working then savepath and if it does not start working then reinstall the Control System Toolbox

It may be because the function you are trying to use is not available in your current MATLAB version. For example, if you use 'normalize' function in any version other than 2018, it will produce the same error, as the 'normalize' function was introduced in MATLAB 2018.

Hello !
I have a matlab function which at a certain point calculates sin(2*pi*freq*t_array) (t_array in an array of size (1,2000).
I tried to call this function vi matlab.engine but I got the error message: "Undefined function 'sin' for input argument of type 'int64' "
I tried what is people suggested in this topic but it didn't work. I wanted to add the file 'sin.m' to my working directory but it is not a function script, it is a simple text.
I would be very grateful of any help
Thank you !

Guillaume il 3 Lug 2019
Please start your own question if you need help. sin is indeed not defined with inputs of type int64. Convert your input to double. If your number is so large that it looses precision when converted to double (i.e. it is greater than flintmax) then why are you calculating the sinus of such large numbers?

  1 Commento
Walter Roberson
Walter Roberson il 7 Feb 2020
There is a series() call in the Control Systems Toolbox but it must be passed control systems not numeric values.
I speculate that you are using series() from some third party code and that it expects some kind of representation of a formula, perhaps symbolic, perhaps a function handle.
One possibility is that you are using symbolic code from r2007a or earlier that was based upon the maple software engine and you passed numeric values instead of symbolic.

R2012b had absolutely no support for Deep Learning.
To do Deep Learning in R2012b, you have two choices:
  1. Write all the code yourself; or
  2. find a third-party library and use loadlibrary() to link to it
The first Deep Learning support was added in R2016a, and there has been a lot of upgrades of the Deep Learning support since that time; if you need to do Deep Learning then I highly recommend that you get a new version of MATLAB.

It is built in to the toolbox, for new enough releases. However you did not mention which release you are using, and it was faster for me to show you where you could find the exact code than it was for us to go back and forth about releases and exactly where the master copy of the code is stored, and exactly which command you are using and so on. I cut through all those steps by giving you a link to the exact code.
