DSSolve#
Solve 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)
Notes#
This call brings the dense system to condensed form. No ordering
of the eigenvalues is enforced (for this, call DSSort() afterwards).
In some DS types, the arguments will hold singular values,
instead of eigenvalues. Singular values are always real.
