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 ?
