Hi ,
I have a mat file with 22 1*1 struct. It took a long time to run all of it. I found that one of the variabels in one of my struct is not correct. I just wanted to replace this by another one which I ran it. Is it possible to replace?
what is the code for doing this?
Thank you in advance.

See matfile: https://www.mathworks.com/help/matlab/ref/matlab.io.matfile.html. It allows making modifications to .mat file without completing loading it. Note that it does not allow to modify struct without completing loading it, so you will at least need to load one of the structs you are trying to modify.

You can simply use the -append option, e.g. where var is the variable that you want to replace:
var = [...];
fnm = 'name of the file.mat';
save(fnm,'var','-append')
