Section 7: Matrix Manipulations

Inverse, Transpose, and Determinant

Example 4

To compute the inverse, transpose, and determinant of a square matrix, we use the  inverse , transpose and  det commands respectively. For example, let us find the inverse of the matrix $A=\left[\begin{array}{cc}1& 2\\ -1& 1\end{array}\right]$ .

To verify the inverse computed above. Let us multiply A with its inverse.

Try this!

Compute the transpose of A by mimicking the syntax used above.
