To compute the trace using R, we use the sum () and diag () functions.

The trace is the sum of the eigenvalues and the eigenvalues of a matrix power are just the eigenvalues to that power. That is, if l_1,...,l_n are the eigenvalues of your matrix then trace (M^p) = 1_1^p + l_2^p +...+l_n^p. Depending on your matrix you may want to go with computing the eigenvalues and then summing.
