X*A=B [SOLVED]

Postby ottapav » Sat Sep 03, 2011 4:46 pm

Hi,
I'm trying to find out how to efficient solve system X*A=B, where A is triangular. My the only one idea is solve throw A'*X'=B' (DTRTRS) but because A and B are parts of only one matrix so I will have to copy and transpose parts...and it seems to be too complicated for such standardized problem. I could''t find but is there any function or algorithm or do you know how to solve?

I totaly overlook that BLAS supports this by function DTRSM. Have a good day.
