I have a large matrix of 6000x10 arrays. I wanted to get some thing like 100 different 60x10 matrices. How can I do that? I can think of a method of cell2mat, in case I do that will I be able to add rows/columns in those cells?

YourArray = randi(9, 6000, 10);
subarrays = mat2cell(YourArray, 60*ones(1,size(YourArray,1)/60), 10*ones(1,size(YourArray,2)/10));
size(subarrays)
ans = 1×2
100 1
size(subarrays{1,1})
ans = 1×2
60 10

Thanks. It worked. Thanks for taking time to reply. Its extemely helpful for my reserach.
I need another help about the cell operation. How can I add those 60 rows with each other in the cell. I meant to say, Row 1 (first cell) + Row 1 (second cell)+...., and repeat it for all 60 rows and get a final 60x10 matrix.

YourArray = randi(9, 6000, 10);
added_together = permute(sum(reshape(YourArray, 60, [], 10),2), [1 3 2]);
which is to say, do not break it into cell arrays if your plan is just to add them together.
If you need the call arrays for other reasons, then
