The condition number of a vector or matrix.

Syntax

c = Cond(m)

Argument

Name

Description

m

A vector or matrix.

Output

Name

Description

c

The condition number.

Example

Find the condition number of a matrix:

Syntax

C = Cond([1,2,3;4,5,6;7,8,10])

Result

C = 88.44823

Comments

The condition number is a measure of closeness to singularity (ill-conditioned) of the matrix. The larger the condition number, the closer it is to singularity.  Inverting a near singular matrix results in significantly inaccurate results.
