| Hi,
|
| i have the following problem: given a 3x3 real matrix, compute exp(A).
|
| I need a really fast way to do this. I have searched a bit with
| google, but it seems to me that
| computing the matrix exponential is not so simple, at least if your
| matrix does not have a special
| structure (for example A=diagonal matrix).

Two procedures in PL/I are to be found at:
