test m-file for fsk modulation

国外编写的一个QPSK仿真程序，给出了调制解调及误码分析(Foreign QPSK simulation program written in a given modulation and demodulation and error analysis)

遗传算法改进的模糊C均值聚类的matlab源程序,可以运行,格式需要更改(Improved genetic algorithm fuzzy C means clustering matlab source code, you can run, you need to change the format)

解决图像配准中遇到的解六个参数的非线性方程组，非常好用。(Solve nonlinear equations of the six parameters of image registration encountered, very easy to use.)

此例程为配套书籍的第六章例题6-5的相对应代码，功能为计算非平稳随机信号的WVD时频谱，编程环境为matlab。(This routine matching books Chapter Example 6-5 corresponding to the code for the calculation of the non-stationary random signal WVD spectrum programming environment for matlab.)

简单的求逆矩阵中单个元素的程序。 用于求解逆矩阵中的单个元素值，基于定义 使用伴随阵/行列式的值求解 只适用于小矩阵。维数太大行列式的值就计算不出来了(Simple inverse matrix of individual elements in the program. For solving the inverse matrix single element values, with the value of the array/determinant of solving only apply to a small matrix-based definition. Value dimension to calculate the determinant is not too out)

此程序是用来将机载激光雷达（LIDAR）点云数据转换成DSM深度影像，以便于后续进行阈值分割工作的。(This program is used for airborne laser radar (LIDAR) to transform point cloud data into the DSM depth image, in order to follow-up the work of the threshold segmentation.)

运用传输矩阵法计算一维光子晶体带隙单缺陷仿真(use TTM calculating the single defect of 1D PC)

matlab basic can be used any where

说明：  一个很有用的函数，功能是产生规定字长以及规定汉明重量的码字，常用于channel coding开发(A useful function, function is to have the provisions of word length and weight of the provisions of Hamming code word, commonly used in the development of channel coding)
