Hey,
I have, A = 208x2 matrix. I wish to to spit this matrix into 104 2x2 matrices. I have tried using num2cell and mat2cell but have had no luck. Any help would be appreicated.
Thanks.

A = rand(208,2) ;
[r,c] = size(A);
nlay = 104 ;
out = permute(reshape(A',[c,r/nlay,nlay]),[2,1,3]);

Split A
A = randi(10, 208, 2) ; % a mtarix of size 208x2
size(A)
B = reshape(A, 2, 2, []) ;
Access 2x2 matrices
B1 = B(:,:,1)
B2 = B(:,:,2)
Hope this helps

Note that this method does not keep the 2x2 matrices of the original matrix:
A = randi(10, 208, 2)
B = reshape(A, 2,2,[]) % not the same matrices
To keep the original matrices requires taing into account the order of elements stored in memory:
B = permute(reshape(A.',2,2,[]),[2,1,3])

Thanks @Stephen23. But he does not mention that the order must be te same as in the original matrix!
