PEPErrorType

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

Synopsis

typedef enum { PEP_ERROR_ABSOLUTE,
               PEP_ERROR_RELATIVE,
               PEP_ERROR_BACKWARD } PEPErrorType;

Values

• PEP_ERROR_ABSOLUTE - compute error bound as \(\|r\|\)

• PEP_ERROR_RELATIVE - compute error bound as \(\|r\|/|\lambda|\)

• PEP_ERROR_BACKWARD - compute error bound as \(\|r\|/(\sum_j\|A_j\||\lambda_i|^j)\)
