快速HLS彩色空间变换方法.caj CAJView打开(Fast HLS color space conversion)

this file implements the set-up of the simulation parameters for wimax matlab simulator. can be used for communications simulations. implemented as a matlab function file. very easy to use

Demo to remove illumination component by homomorphic filtering. Some functions used here require Image Processing Toolbox and Signal Processing Toolbox

Demo of Hough Transform for straight lines This assumes that the Sussex vision library is in your Matlab path.

说明：  直接序列扩频系统中m序列产生的程序代码，此程序清楚明白(Direct Sequence Spread Spectrum System m sequences generated code, this procedure clear)

说明：  比较全面的MATLAB编程教案，共十四个PPT涵盖MATLAB编程各方面。(MATLAB programming more comprehensive lesson plans, a total of fourteen PPT covers all aspects of MATLAB programming.)

一般的esprit算法好的时间比较大，在计算子空间是算法比较烦，我改了一些矩阵算法。(general esprit algorithm good time, the calculation algorithm is a subspace trouble, I changed some matrix algorithm.)

压缩文件包含两个matlab程序，m_sequence.m是子函数，功能是根据本原多项式生成对应的m序列，m_sequence_nature.m是主函数，调用m_sequence.m生成m序列并验证m序列的特性。(Zip file contains two matlab program, m_sequence.m a subroutine, function is a polynomial to generate the corresponding m-sequence according to the primitive, m_sequence_nature.m is the main function, call m_sequence.m m sequence generation and validation features m sequences.)
