function [y,i]=fmax(w,f)
%FMAX   Maximum of MVFR matrix
%       FMAX(W,F) applies MAX to each component matrix of
%       the MVFR matrix, F, and returns one row per frequency.
%
%       [Y,I]=FMAX(W,F) also returns the indices of the
%       maximum elements in each component matrix.
%       See MAX,FMIN
