I *Think* this means that a bottlleneck here is svd, which is being
called by this function that calculates generalized inverses:
## Moore-Penrose Inverse function (aka Generalized Inverse)
## X: symmetric matrix
## tol: convergence requirement
mpinv <- function(X, tol = sqrt(.Machine$double.eps)) {
s <- svd(X)
e <-...
