How to load and plot mat file python.

On the other hand the function can load data from a matlab mat file this is matlab s own data format within which you store variables and data but not code. Name of the mat file do not need mat extension if appendmat true. These are matlab s own script files and they contain matlab code. Could anyone please let me know that why i can t plot this spectrum mat file kindly if someone show me the procedure for plotting mat files.

You may have a mat file that you want to read into scipy. Dr manab 429 views. You cannot load m script files. You can get the file used in this post here.
