Linprog Error MATLAB R2017B

Hi, I've been encountering the following linprog error from my laptop:

"Attempt to execute SCRIPT linprog as a function:

Error"

Even when I used the codes from the link attached, I still get the same error code. https://www.mathworks.com/help/optim/ug/linprog.html

Hi,

see this:

https://de.mathworks.com/matlabcentral/answers/93148-why-do-i-receive-the-error-attempt-to-execute-script-filename-as-a-function

i guees on your new machine there is a script named linprog.m

to check use:

which linprog -all

There should only be one result, namely in the Matlab directory of the optimization toolbox:

>> which linprog
C:\Program Files\MATLAB\R2018a\toolbox\optim\optim\linprog.m

This is an example on my machine. If you have more than one results rename or delete the script(s) which are not in the optimization toolbox:

>> which linprog -all
C:\Users\stephan\Documents\MATLAB\projects\linprog.m
C:\Program Files\MATLAB\R2018a\toolbox\optim\optim\linprog.m  % Shadowed

This example will cause problems.

Best regards

Stephan

This answer might be helpful.

There would be filename conflict in your custom script and built-in linprog. Could you confirm whether you have created linprog.m in your MATLAB paths.

 which -all linprog

If you find linprog.m in a folder which is not MATLAB installation folder, please rename the file to avoid file name conflict.
