FFT2

基于matlab的无刷直流电机仿真速度PI，电流PI双闭环仿真(Matlab-based simulation of brushless DC motor, using speed PI, current PI double closed loop control.)

Contourlet变换中的隐马尔科夫树模型程序 Hidden Markov Tree model of Contourlet Transform 2008年11月14日 MATLAB2 (R2006a) 这是一个Matlab实现的隐马尔科夫树模型，用于计算图像的Contourlet系数。程序同时还包括图像去噪、纹理恢复的应用模型。(Contourlet transform the hidden Markov model procedures for Hidden Markov Tree model of Contourlet Transform 2008 年 11 月 14 日 MATLAB2 (R2006a) is a Matlab implementation of the Hidden Markov Tree Model, used to calculate the image Contourlet factor. Program also includes denoising, texture recovery application model.)

说明：  带通滤波。该程序用matlab实现梯形窗的带通滤波，可以直接调用(Band-pass filter. Trapezoidal matlab implementation of the program window with a band-pass filter, can be called directly)

根据读取到的已知控制点的坐标，计算在该区域内的平面转换五参数，该五参数不同于当前使用较多的四参数(According to the known control point to read the coordinates to calculate the plane in the region converted five parameters, the five parameters to use more different from the current four-parameter)

本程序不能编译除大小写字母之外的编码 本程序需事先建立字母权值文后件才可运行 本程序从文件中读入文字，编译后写入文件，所以屏幕上不会直接出现答案(not build this program in addition to case-insensitive outside of the coding process required prior to the establishment of the letters after the value of the text pieces can Win OK this program read from the file into the text, compiled into the paper, not directly on the screen appeared the answer)

SAR成像很好的学习资料，希望大家喜欢。(The SAR imaging learning materials, hope you like)

说明：  C++矩阵运算,可以像matlab那样轻松使用(C++ matrix computation)

程序设计问题和学习有效题目，可以有效提高初学者学习能力。(it can inprove the ability of the learners)

Listing is a program for sorting algorithms using the heaps sort and binary search sorting.

遗传算法的一个07版本，可以让初学者有入门，让有一定基础的同志有进阶。(07 version of a genetic algorithm that allows beginners get started, so that some comrades are based Advanced.)
