### of use to both students and instrutors

This is a very nice outline of how to develop the concept of the matrix exponential. It should be of use to both students and instructors since it uses a sequence of $2 \times 2$ matrices which provided more sophisticated ideas to obtain the matrix exponential.

### Cookbook approach to matrix exponential

Cookbook approach to matrix exponential, with lots of examples of its calculation. No proof of existence; several typos. Includes interesting method of calculation (with justification) when matrix is not diagonalizable.
