编辑： MarshallSc 2022-1-19

I have this 10x10 cell array:

I want to reshape it into a 4x4 cell each containing a 10x10 matrix keeping the order of each value in the matrices. For example, the first new cell ( cell(1,1) ) contains the first values of the 16x1 matrices which will transform into a 10x10 for each cell and so on. I'd appreciate it if someone can please help me! Thank you!

There are probably other ways, but...
