How many ways to compute Rank of Matrix by using IMSL Library?

Hi,

I am stuck on Rank of Matrix problem which was posted at http://software.intel.com/en-us/forums/topic/455978;  there was no reply :(

I am trying to attempt other way to compute it such as RANK (A), LSVRR (NRA, NCA, A, LDA, IPATH, TOL, IRANK, S, U, LDU, V, LDV); however, it seems could not solve my whole problem perfectly.

Could you please suggest any other way to compute Rank of Matrix by using IMSL?

By the way, is there any email address of Technical Team Support where I can send my inquiries?

Thank you in advance.
