Installation of eeglab2023.0 renders certain statistical functions in MATLAB, such as ttest2, unusable.

Can you please provide a solution to this issue?

I have this problem with Eigenvector's PLS toolbox. There are several functions (skewness, dataset, etc.) that they claim they wrote before functions of the same name were introduced by Mathworks and they refuse to change them. If you know you will always want the MATLAB version and never want the EEGLAB version of the function, then you can move the EEGLAB paths down below the toolbox paths. Use the SetPath button on the Home tab of the toolribbon to move the paths down.

If sometimes you want EEGLAB functions and sometimes the MATLAB versions of those functions then you can rename the EEGLAB functions and call them in your code by the new name instead of the original EEGLAB function name. Like preface the shadowed functions with "eeg" or something.

EEGLab is changing the path for some reason. You can either search the source code for strings like "rmpath", "path", "savepath", "addpath", etc. Or you can contact the publisher and ask why their program removes the stats toolbox from the path.

Thank you for your response.

I will contact publisher .
