condeig - Condition number with respect to eigenvalues
Syntax
c = condeig(A)
[V,D,s] = condeig(A)
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
[V,D] = eig(A);
s = condeig(A);
Large condition numbers imply that A is near a matrix
with multiple eigenvalues.
