matexpo: Matrix Exponential
In gjuggler/ape: Analyses of Phylogenetics and Evolution

This function computes the exponential of a square matrix using a spectral decomposition.

1	matexpo(x)

`x`	a square matrix of mode numeric.

a numeric matrix of the same dimensions than ‘x’.

### a simple rate matrix:
m <- matrix(0.1, 4, 4)
diag(m) <- -0.3
### towards equilibrium:
for (t in c(1, 5, 10, 50)) print(matexpo(m*t))
