Condition number with respect to eigenvalues

Syntax

Description

c = condeig(A) returns a vector of condition numbers for the eigenvalues of A. These condition numbers are the reciprocals of the cosines of the angles between the left and right eigenvectors.

[V,D,s] = condeig(A) is equivalent to

Large condition numbers imply that A is near a matrix with multiple eigenvalues.
