How to save two matrices A and B in single .mat file using a loop (A and B changes for each operations)?

I have two matrices A and B. every time these matrics changes with some operations on image. So I would like to save them in a single .mat file using a loop, so that each .mat file will be saved in different name. now I want to load 1) .mat file using a loop 2) from .mat file I need to load A and B matrices separately for next operations.
how to do that? in other words how to save workspace in a loop and load them back using a loop?

Here is one way:
for i = 1:3
A = rand(4);
B = rand(5);
filename = ['file',sprintf('%d',i),'.mat'];
save(filename,'A','B')
end
This will save each of the newly created A and B into files named "file1.mat", etc.
Unless A and B are prohibitively large, perhaps a better way to do this would be to save your matrices into cell arrays, and save the cell array:
for i = 1:3
A{i} = rand(4);
B{i} = rand(5);
end
save('file.mat','A','B')

thank you it's a good way to save array into the mat file
