Inconsistent results with Pardiso

[Rawlins__David]

Hi,

I'm getting inconsistent results from one run to another with Pardiso and the same input file. I'm assuming it's due to an ill conditioned matrix, but I'm wondering if there may be something else that may be causing the inconsistent results.

Thanks,

Dave

Dave,

what do you mean by inconsistency? I saw some posts from people expecting bit-by-bit identical results, which for Pardiso you won't get.
In general, if the matrix is ill-conditioned, you should go along SVD path and not Pardiso.

Thanks, I'll look into SVD.
