Here is the thing: I plan to do HMM analysis on Matlab by HMM-MAR toolbox. At the first time, I downloaded the HMM-MAR toolbox on the website: GitHub - OHBA-analysis/HMM-MAR: Toolbox for segmentation and characterisation of transient connectivity. Then the command window of MATLAB just told me: the MEX file was not used. I searched that this file will help me speed the analysis process. Then I asked chatGPT to help. It told me that there is HMM-MAR/utils/mex/mexHMMmar.c file in the github. But I cannot find this file eventhough the chatgpt insist on this things.If I cannot use the MEX file, it will takes 10 days at least to run my script.
