KSPSolveTranspose

Solves the transpose of a linear system. Usually accessed through SLESSolveTranspose().

Synopsis

#include "petscksp.h" 
int KSPSolveTranspose(KSP ksp,int *its)

Collective on KSP

Input Parameter

ksp -iterative context obtained from KSPCreate()

Output Parameter

its -number of iterations required

Notes

On return, the parameter "its" contains either the iteration number at which convergence was successfully reached, or the negative of the iteration at which divergence or breakdown was detected.

Currently only supported by KSPType of KSPPREONLY. This routine is usally only used internally by the BiCG solver on the subblocks in BJacobi and ASM.
