Hi,
I have a program which it's output is 22*22 cell. It took a long time to run. Now, I saw that in one struct and one variables there is a missed matrix. I can run the program for this specific day but if i can put the result in its place in that cell struct or not?
how is it possible to put new run in the same mat file?
Thank you in advance.

Do you want to avoid loading the mat file in memory? matfile(): https://www.mathworks.com/help/matlab/ref/matlab.io.matfile.html does provide the option to modify the .mat file directly, but It has not allowed to cell indexing into cell array or struct fields.

If you build the cell content, there's no reason shouldn't be able to just assign it to the cell array where it belongs.
Then just rewrite the new variable to .mat file.
Of course, save a copy of the present file as backup first just in case you have a slip of the fingers...

Thank you so much.
Done!!!
I just loaded my previouse mat fie and then run the program for that specific day and finally assign it to the cell array where it belongs.
