Determines the type of extraction technique employed by the eigensolver.

Synopsis

typedef enum { EPS_RITZ,
               EPS_HARMONIC,
               EPS_HARMONIC_RELATIVE,
               EPS_HARMONIC_RIGHT,

Values

• EPS_RITZ - Rayleigh-Ritz extraction

• EPS_HARMONIC - harmonic Ritz extraction

• EPS_HARMONIC_RELATIVE - harmonic Ritz extraction relative to the eigenvalue

• EPS_HARMONIC_RIGHT - harmonic Ritz extraction for rightmost eigenvalues

• EPS_HARMONIC_LARGEST - harmonic Ritz extraction for largest magnitude (without target)
