PEPConv#

The convergence criterion to be used by the solver.

Synopsis#

typedef enum { PEP_CONV_ABS,
               PEP_CONV_REL,
               PEP_CONV_NORM,
               PEP_CONV_USER } PEPConv;

Values#

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

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

  • PEP_CONV_NORM - convergence criterion relative to matrix norms, \(\|r\|/(\sum_j\|A_j\||\lambda|^j)\)

  • PEP_CONV_USER - convergence dictated by user-provided function
