**Finding a Multiplicative Inverse Matrix**

To obtain A^{-1} for any n n matrix A for which A^{-1} exist, follow these steps.

**a.** From the augmented matrix [A | I ], where I is the n n identity matrix.

**b.** Perform row operation on [A | I] to get a matrix of the form [I | B], if this is possible.

**c.** Matrix B is A^{-1}.
