matrix logarithms

Postby illconditionedmatrix » Fri Jul 29, 2011 1:43 pm

Hi everyone,
I am trying to implement a function which uses logarithm of a matrix as an
intermediate step. Basically, I am converting from Matlab code, and I need
an LAPACK routine equivalent to logm() in matlab. I have searched around and
have not been able to locate any LAPACK function that dies this directly, but then,
I have just started with this, and may have missed it in the function set. Can someone
let me know if such a functionality esixts, or a combination of functions that
I can use to implement logm() using a set of primitives available in LAPACK?
