<div dir="ltr"><div id="result_box" dir="ltr">Hello, <br><br>
I have problems with the implementation of a user-defined pc, basically
my program is in a cycle, for with which he is called by matlab each
time it seeks to solve a linear system, the problem is that in the
first iteration of the for-cycle the preconditioner works very well,
then fails to convergence. It may be some parameters that I setting
wrong? <br> I'am attaching my program code.<br><br>Thank you,<br><br>Michel<br></div></div>
