This question is simple
I understand that MATLAB solves sparse linear equations by multi wavefront method on CPU
like sparse_a Is a sparse b is a full vector then x can be computed by x=sparse_a\b
is there any method to let matlab compute sparse in gpu?
gpu_sparse_a=gpuArray(sparse_a ) b_gpu=gpuArray(b)
and then x=gpu_sparse_a\b_gpu
result shows that gpu compute sparse slower than cpu....why?is sparse in cpu transfer into gpu actually become a full matrix?
