TaoGetConvergenceHistory

Gets the array used to hold the convergence history.

Synopsis

#include "tao_solver.h"  
int TaoGetConvergenceHistory(TAO_SOLVER tao, double **a, int **its,int *na)
Collective on TAO_SOLVER

Input Parameter

tao -the TAO_SOLVER solver context

Output Parameters

a - array to hold history
its - integer array holds the number of linear iterations (or negative if not converged) for each solve.
na - size of a and its

Notes

The calling sequence for this routine in Fortran is
  call TaoGetConvergenceHistory(TAO_SOLVER tao, integer na, integer info)

This routine is useful, e.g., when running a code for purposes of accurate performance monitoring, when no I/O should be done during the section of code that is being timed.
