[petsc-users] dense matrix problem

[Alex Salazar]

Hello, everyone

I want to get the solution of algrebraic system (with a  dense
zero-diagonal simetric matrix) of a interpolation problem (using radial
basis functions) with Petsc.

 For a few points (around 10 elements) using KSP I get the correct
solution,  however when  I increase the number of points,  the result is
incorrect.

Any Idea ?

Regards Alejandro.
