## let’s look at an example of the SN decomposition.

This comes from Perko p. 35, example 3. We will compute exp(A) using the SN decomposition described in the previous post (“1 of 3”).

We take the following matrix:

I ask Mathematica® to find its eigenvalues and eigenvectors. For eigenvalues, I get

For the eigenvector matrix, I get
