See: http://www.nabble.com/implementation-of-matrix-logarithm-%28inverse-of-matrix-exponential%29-ts25628876.html Also, some good advice for finding a function when you don't know it's name but you do know what job it performs is to have R search all the help pages in all the packages you have using the ?? command: ??'matrix exponential' You will see the expm() function in the base package Matrix if you have a newish version of R.
