<div dir="ltr">Hello, everyone <br><br>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.<br><br> 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.<br>
<br>Any Idea ?<br><br>Regards Alejandro. <br><br></div>
