- Do you receive warning and/or error messages? If so the full and exact text of those messages (all the text displayed in orange and/or red in the Command Window) may be useful in determining what's going on and how to avoid the warning and/or error.
- Does it do something different than what you expected? If so, what did it do and what did you expect it to do?
- Did MATLAB crash? If so please send the crash log file (with a description of what you were running or doing in MATLAB when the crash occured) to Technical Support so we can investigate.

Dear all,
For some reasons I had to reboot my machine and reinstalled Matlab, version 2022b.
I tried to run my previous and validated program but the function is raising an issue of type of the input arguments, which never happened before...
Even the examples of the help page do not work:
x = [1,2,3,4];
y = upsample(x,2)
So I am a bit pissed off...
Anyone has suggestions?
Thanks a lot in advance.
Best regards,
louis tomczyk

What does "not working" mean in this context?

I can find two upsample functions in the online documentation, one in the Signal Processing Toolbox (that should work with your code) and another one in the Control System Toolbox that will definitely not work with the posted code, since it requires a ‘system’.object as the first argument.
x = [1,2,3,4];
y = upsample(x,2) % Signal Processing Toolbox 'upsample'
Be certain that you have the Signal Processing Toolbox licensed and installed.
If you have it and you are still getting the error, run:
which upsample -all
from a script or the Command Window. The result should look something like this.
If there is anything else, it would reveal a user-written function that is overshadowing the one you want to use. The solution is to rename the user-written function to something that makes sense in the context of your code and does not match any built-in MATLAB function names.
