A Matlab Tour of Second Generation Bandelets 附有每部分代码的说明 function x = perform haar transform(x, dir); x = x(:); % to be sure we have a column vector J = floor( log2(length(x)) ); % number of scales if dir==1 % forward transform for j=1:J c = x(

This program is open source code of fast Fourier transform in matlab. Where y is the input argument and p is the normalized size of the input. Let y = [1 2 3 4 ] x= length(y) m= log2(x) p= ceil(m) To call the function use ft2(y,p
