Trying to run on newly install Matlab R2021a with Psychtoolbox-3
[x,rect] = Screen(0,‘OpenWindow’);
Error message:
In place of the expected mex file this placeholder file was executed:
Screen
This mex file seems to be missing or inaccessible on your Matlab path or it is dysfunctional:
Screen.mexw64
Hmm. I cannot find the file on your Matlab path?!?
One reason could be that your Matlab path is wrong or not up to date
for the current Psychtoolbox. You may want to run SetupPsychtoolbox to
fix possible path problems.
