Returns the performance index of a real symmetric eigensystem.

Parameters

a

A double symmetric matrix.

Return Value

A double scalar value indicating how well the algorithms which have computed the eigenvalue and eigenvector pairs have performed.

Remarks

A performance index less than 1 is considered excellent, 1 to 100 is good, while greater than 100 is considered poor.
