Example of Condition Number
Let $\mathbf A$ be the coefficient matrix of a system of simultaneous linear equations.
A condition number for $\mathbf A$ is:
If the system of simultaneous linear equations is ill-conditioned, $\mathbf A^{-1}$ will have relatively large elements and the condition number will likewise be large.
