Compute multivariate mode indicator function for single reference input.
mif = simo_mmif(f)
SIMO_MMIF will compute the multivariate mode indicator functions from the frequency response functions in the supplied imat_fn F. One multivariate MIF will be computed for each reference in F. If specified, MMIF will be calculated using response dof in imat_ctrace CT.
