NEPErrorType#

The error type used to assess the accuracy of computed solutions.

Synopsis#

typedef enum { NEP_ERROR_ABSOLUTE,
               NEP_ERROR_RELATIVE,
               NEP_ERROR_BACKWARD } NEPErrorType;

NEP_ERROR_ABSOLUTE - compute error bound as \(\|r\|\)
NEP_ERROR_RELATIVE - compute error bound as \(\|r\|/|\lambda|\)
NEP_ERROR_BACKWARD - compute error bound as \(\|r\|/(\sum_i|f_i(\lambda)|\|A_i\|)\)
