DSSolve#

Solves the problem.

Synopsis#

#include "slepcds.h" 
PetscErrorCode DSSolve(DS ds,PetscScalar eigr[],PetscScalar eigi[])

Logically Collective

Input Parameters#

  • ds - the direct solver context

  • eigr - array to store the computed eigenvalues (real part)

  • eigi - array to store the computed eigenvalues (imaginary part)

Note#

This call brings the dense system to condensed form. No ordering of the eigenvalues is enforced (for this, call DSSort() afterwards).
