[Numpy-discussion] Matrix exponential

[Nils Wagner]

Hi,

Has anyone written some functions concerning the matrix exponential
expm(A) ?

I am looking for demos illustrating the use of Padé approximation,
Taylor series approximation, and eigenvalues and eigenvectors,
respectively, to compute the matrix exponential.

Thanks in advance.

Nils
