EPSCISSQuadRule

The quadrature rule used in the EPSCISS solver.

Synopsis

typedef enum { EPS_CISS_QUADRULE_TRAPEZOIDAL = 1,
               EPS_CISS_QUADRULE_CHEBYSHEV   = 2 } EPSCISSQuadRule;

Values

• EPS_CISS_QUADRULE_TRAPEZOIDAL - trapezoidal rule

• EPS_CISS_QUADRULE_CHEBYSHEV - Gauss quadrature on Chebyshev points
