This LDPC software is intended as an introduction to LDPC codes computer based simulation. The pseudo-random irregular low density parity check matrix is based on Radford M. Neal’s programs collection, which can be found in [1]. While Neal’s collection is well documented, in my opinion, C source codes are still overwhelming, especially if you are not knowledgeable in C language. My software is written for MATLAB, which is more readable than C. You may also want to refer to another MATLAB based LDPC source codes in [2], which has different flavor of code-writing style (in fact Arun has error in his log-likelihood decoder).

基于遗传算法的优化调度，调度是电力系统的调度，现在应用很广泛。(Based on Genetic Algorithms The scheduling is to schedule the power system, which is widely used now)

雷达信号处理、雷达检测，波形 ，信噪比，波形检测(Radar signal processing, radar detection, waveform, signal to noise ratio)

本程序用于三维坐标绕原点旋转之后的点坐标位置，初始坐标自行设定。(This program is used to coordinate the position of the origin of the three-dimensional coordinates of the point of rotation around after the initial coordinates to set their own.)

对归一化后的RGB图片空间转化为hsi空间,hsi三分量也是归一化后的值,范围都是在0-1之间.(On the normalized RGB image space after hsi into space, hsi is also a three-component normalized values are in the range between 0-1.)
