function f=fdly(w,f,dly)
%FDLY   Adds delays to MVFR matrix.
%       FDLY(W,F,DLY) returns an MVFR matrix
%       in which each component matrix of the MVFR matrix
%       F has been multiplied element-wise by exp(-j*w*dly).
%       The matrix DLY specifies the delay in seconds
%       for each element of F.
