FRAMEGRAM - Easy visualization of energy in transform domain

Program code:

function framegram(F,x,varargin)
%FRAMEGRAM  Easy visualization of energy in transform domain
%   Usage: framegram(F,x,...);
%
%   FRAMEGRAM(F,x) plots the energy of the frame coefficients computed
%   from the input signal x using the frame F for analysis. This is
%   just a shorthand for:
%
%     plotframe(F,abs(frana(F,x)).^2);
%
%   Any additional arguments given to FRAMEGRAM are passed onto
%   PLOTFRAME.
%
%   See also: plotframe
