how to sort this error?
Use which -all on the name that MATLAB says was a script that you expected to be a function. More likely than not you've defined your own file with the same name as a function in MATLAB or another MathWorks product and so your file is shadowing (taking precedence over) the function in the MathWorks product. Rename your file or remove it.
As an example, if I created a script file plot.m:
% Change to a new temporary directory into which I can write the file
newlocation = tempname;
mkdir(newlocation)
cd(newlocation)
% Create the file using low-level file I/O functions
fid = fopen(fullfile(pwd, 'plot.m'), 'wt');
fprintf(fid, "x = 1+1");
fclose(fid);
and ask what plot refers to:
which -all plot
I see the script I just created is the first item on the list. [I also receive warnings.]
You can see that the plot.m file MATLAB finds first is the one I created:
type plot.m
I can run that script without a problem:
plot
but if I try to call the plot function included in MATLAB I receive an error.
plot(1:10, 1:10)
If I were to delete the plot.m script, I would be able to call the plot function in MATLAB.

Hi Jonathan,
Aforementioned error occurs as plot is already an internal implemented function in MATLAB. You may check if there is any internal implementation already done for any specific function using which commmand:
which plot -all
This problem can be resolved by using a different filename for the current script, which is not already used for any other internal function in MATALB.

Hi, I've came across the same error in MATLAB and I've changed the flinename for the script multiple times but it doesn't fix the issue.
For the script that is listed in the error message you receive, what does the command posted in the accepted answer show when you run it using that script name? So if your error message says that "Execution of script max as a function is not supported" (instead of plot) you would type:
which max -all

Nobody knows what your filenames/path are, what errors you're seeing, or what you tried to do to fix it. It's up to you to describe the problem you have.
Is the error the same error as in the title? If so, what's the output of which()?

Hi, change your file name from plot.m to another thing will work.

Hi, Jonathan,
I had the same issue which has been solved now. The reason is that he name of my script is plot.m which same as one of the MATLAB function (plot) names. After I change it the output is normal. You can change the script name like test.m and try again.
