MULTVAR <covariance_matrix_S>,L computes a variability measure Mvar(S) of S.Mustonen (1995). By default, the stepwise method is used. The exhaustive method is selected by METHOD=EXHAUSTIVE. The accuracy parameter in Cholesky decompositions is set by EPS=eps (Default EPS=0.000001). The optimally permuted covariance matrix is saved as a matrix file COVVAR.M . Reference: S.
