NEPConv#

The convergence criterion to be used by the solver.

Synopsis#

typedef enum { NEP_CONV_ABS,
               NEP_CONV_REL,
               NEP_CONV_NORM,
               NEP_CONV_USER } NEPConv;

Values#

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

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

  • NEP_CONV_NORM - convergence criterion relative to matrix norms, \(\|r\|/(\sum_j|f_j(\lambda)|\|A_j\|)\)

  • NEP_CONV_USER - convergence dictated by user-provided function
