function [m,n]=fsize(w,f)
%FSIZE  Size of MVFR matrix.
%       FSIZE(W,F) checks the MVFR matrix, F, for
%       consistency with the associated frequency vector W
%       and returns the size vector of the component matrices of F
%
%       [m,n]=FSIZE(W,F) returns the number of rows of the
%       component matrices in m and the number of columns in n.
