Description

The Reciprocal Condition block computes the reciprocal of the condition number for a square input matrix A.

y = rcond(A)         % Equivalent MATLAB code

or

where is the condition number ( 1), and y is the scalar sample-based output (0 y < 1).

The matrix 1-norm, , is the maximum column-sum in the M-by-M matrix A.

For a 3-by-3 matrix:
