condition number defines c as the following equation:

c = ||A||p||A–1||p

where ||A||p is the norm of Input Matrix. Different values of p define the different types of norms, therefore p defines different types of computations of condition numbers.

For the 2-norm condition number, c is the ratio of the largest, singular value of A to the smallest, singular value of A.

The condition number of a matrix measures the sensitivity of a system solution of linear equations to errors in the data. It gives an indication of the accuracy of the results from a matrix inversion and a linear equation solution.
