### Matrix equilibration

Posted:

**Tue Apr 30, 2013 1:24 am**Hello!

I wanted to try to convert some matrix calculations from MKL to CUDA. My problem involves some matrix multiplications and additions and finally the solution of a linear equation system.

Unfortunately, the condition of the matrix seems to be very high and the solution of the equation system with MKL's zgesv was unsuccessful. As a result of this, I switched to the expert driver zgesvx. This routine equilibrates the matrix and solves the resulting equation system.

So my question is, if there is a possible workaround or any plans to include routines for matrix equilibration (especially the routine ?gesvx or the general routine ?geequ would be of interest).

Best Regards,
