Compute Cholesky Root of Matrix
This decomposition is a mathematical method for taking the square root of a symmetric matrix. The Cholesky root of a matrix A is L, where A = LL`, and L is a lower-triangular matrix. It is useful in QTL analysis because it allows modeling of a pedigree-induced covariance structure via a mixed model.
