Hello,

Thanx a lot for this great component.. Im using Bicgstab method with diagonal preconditioner to solve 16000*16000 matrix.. It takes about 53 seconds and im also using MKL library to speed up this.. Can anyone suggest me a method to increase the speed... Thanx in advance...  :)

16 000×16 000 is a kida beast matrix, how fast does MatlLab do it?

Hi Bumper..

can you tell us  which underlying problem you are trying to solve..other than inverting the giant matrix? Perhaps there are other ways to get to to a close enough answer, not sure if there is thoug.
