Although looking for into the Class Index I haven’t found such a function, I wanted to ask you if there is a direct way of computing the matrix exponential, i.e.,
exp(M), with M a square matrix in the TMatrixT class.
In principle, I know that I could diagonalize the matrix and then I would get its exponential by computing the exponential of the diagonal elements. However, I wonder if there is a faster (direct) way to do it.
Thanks for your help.
