Attempt to execute SCRIPT interp2 as a function:

Hi,

I a trying to run a code while I get this error.

Attempt to execute SCRIPT interp2 as a function:

/Applications/MATLAB_R2020a.app/toolbox/matlab/polyfun/interp2.m

Error in TMD_calculate (line 89)

D=interp2(X,Y,H',xt,yt);D=D';

while either there is no script and a function that both exist on this same path or there is not even a script of that overall.

I will be thankful if you let me know how I can solve that.

Please show us the output of this command:

which interp2 -all

[Seyedeh Fardis]

which interp2.m -all

/Applications/MATLAB_R2020a.app/toolbox/matlab/polyfun/interp2.m

/Applications/MATLAB_R2020a.app/toolbox/parallel/gpu/@gpuArray/interp2.m % gpuArray method

[John D'Errico]

Did you mistakenly edit interp2, and then save it, after deleting the function header?

Are you POSITIVE there is no script by that name? What happens when you do this? I'm sorry, but I've seen the claim before, and it was pretty much always wrong.

which interp2 -all

Did you download something that has an interp2 script in it?

The point being, if MATLAB tells you interp2 is a script, then MATLAB sees a script by that name. However that script was created, there is something called interp2 on your path, and it is a script. MATLAB has no reason to lie in this.

[Seyedeh Fardis]

which interp2.m -all

/Applications/MATLAB_R2020a.app/toolbox/matlab/polyfun/interp2.m

/Applications/MATLAB_R2020a.app/toolbox/parallel/gpu/@gpuArray/interp2.m % gpuArray method

[John D'Errico]

As I suspected from your comments, there is indeed a scripted version of interp2. Not an obvious one, but it was there after all. The point is, that error is impossible to arrive at, UNLESS there is a script named interp2.

[Raymond Norris]

Run

edit /Applications/MATLAB_R2020a.app/toolbox/matlab/polyfun/interp2

and show us what the first couple of lines look like.

The error message

Attempt to execute SCRIPT interp2 as a function:
/Applications/MATLAB_R2020a.app/toolbox/matlab/polyfun/interp2.m

tells us that MATLAB is trying to run /Applications/MATLAB_R2020a.app/toolbox/matlab/polyfun/interp2.m, but sees it as a script.

[Seyedeh Fardis]

so I used edit /Applications/MATLAB_R2020a.app/toolbox/matlab/polyfun/interp2

and the code showed up. I ran it and I got this error again ! :

Attempt to execute SCRIPT interp2 as a function:

/Applications/MATLAB_R2020a.app/toolbox/matlab/polyfun/interp2.m

Error in interp2 (line 40)

u_interp = interp2(x, y, u(y), X, Y, 'linear');

[Raymond Norris]

Run

dbstop if caught error

this might catch too many errors initially, but somethings not right. interp2 (line 40) is a comment, but your error message shows a call to interp2.

Once you land in the file interp2, run

dbstack

Copy and paste the response. This will tell us where the other interp2 is being found.

[Walter Roberson]

The first line of interp2 should be

function Vq = interp2(varargin)

I would suggest

dbstop if error

rather than

dbstop if caught error

[Seyedeh Fardis]

You mean when I get the error run dbstack? if you mean that I get this:

While at that break point, what does

which interp2

return? Also, what does

which -all pathdef

return?

[Seyedeh Fardis]

Oh no !

It doesn't have this: function Vq = interp2(varargin)

It is opening one of my old project code but I don't know why that project is in this path! How I can get this one that you are saying in this path?

[Seyedeh Fardis]

which interp2

/Applications/MATLAB_R2020a.app/toolbox/matlab/polyfun/interp2.m

which -all pathdef

/Applications/MATLAB_R2020a.app/toolbox/local/pathdef.m

[Raymond Norris]

My guess is that at some point your code is changing directories, specifically to the location of where the old project code lives, and is finding your interp2 (which is why MATLAB isn't finding it with which -all -- since it's not really on the MATLAB path). The solution here is to rename your interp2 to something else.

Or you have added your project to the path (but then which -all should have found it). The solution here is to edit your path to no longer include it (HOME > Set Path. Select folder, then click Remove and Save).
