EPSConv

The convergence criterion to be used by the solver.

Synopsis

typedef enum { EPS_CONV_ABS,
               EPS_CONV_REL,
               EPS_CONV_NORM,
               EPS_CONV_USER } EPSConv;

Values

• EPS_CONV_ABS - absolute convergence criterion, \(\|r\|\)

• EPS_CONV_REL - convergence criterion relative to eigenvalue, \(\|r\|/|\lambda|\)

• EPS_CONV_NORM - convergence criterion relative to matrix norms, \(\|r\|/(\|A\|+|\lambda|\|B\|)\)

• EPS_CONV_USER - convergence dictated by user-provided function
