How to speed up huge matrix mldivide? I was solved this matrix on single core but it took too long. So, i was used distributed array using parallel computing tool box, but i didn't get speed up. Using distributed array took too long than single core. How to speed up solution.

distributed arrays on a single machine will generally perform worse than normal arrays - this is because the standard MATLAB mldivide is already intrinsically multithreaded.
If you have access to a capable GPU, and your problem fits in the memory of the GPU, this might be a good option. See this example which compares mldivide performance on the CPU and GPU.
