"How collect three different .mat files in one .mat file?"

It depends on things that you have not told us: do the variables is each .mat file have the same names, or different names? Do you want them concatenated into one array, or kept as separate arrays? If you dont't tell us these things, we have to guess... and guessing is not the best way to help you.

Dears @Stephen @madhan sorry about that. all .mat files are feature numbers.they are three different class of image observation but I applied the same 10 features for all (30 images in class 1,30 images in class 2,30 images in class3). I want to concentrate on one matrix array(90x10)

Just load the data. Once you can see all the variables in workspace, just write

save('file.mat')
