This matlab code runs a canny edge detector.

lear N = 10^5 EB_NO = [-1:30] liu1 = zeros(1,N) liu2 = zeros(1,N) for ii = 1:length(EB_NO) m= (2*(rand(1,N)>0.5)-1) + j*(2*(rand(1,N)>0.5)-1) s = (1/sqrt(2))*m normalization of energy to 1 n = 1/sqrt(2)*[randn(1,N) + j*randn(1,N)]

学习matlab的好资料,是你学习的好助手，你可以用来学习matlab和数学建模(this is a learn matlab very good )

各种基本matlab实例精讲，以及详细的关于DFT的设计及其算法(Examples of basic matlab succinctly, and detailed design of algorithms for the DFT)
