How can I define an array of sparse matrix? (both for GPU and CPU)

A=sparse(3,3)
MT=gpuArray(A);
M2(1,1)=1
%Error using gpuArray/subsasgn
%Sparse gpuArrays are not supported for this function.
L=sparse(3,3,1);
L(:,:,1)=A;
%N-dimensional indexing allowed for full matrices only.
L2=gpuArray(L);
L2(:,:,1)=MT;
%Error using gpuArray/subsasgn
%Sparse gpuArrays are not supported for this function.

For CPU, you can use the ndSparse submission by Matt J on the FEX:
I am unaware of anything similar for GPU.

See example below for sparse on GPU:
sparse(A1,A2,gpuArray(1),m1,m2);
sparse(41200,41200,gpuArray(1),41200,41200);
- first 2 arguments for size, last two for memory,
- there should be always A1<m1 & A2 <m2
