最经典的matlab介绍微粒群算法的书，不好买的。(The most classic PSO algorithm matlab introduction of the book, not bought.)

这个程序可以实现一个正态总体参数的假设检验问题(This program can realize hypothesis test of a normal population parameter )

这是一个课程设计的MATLAB代码，他是一个利用尺度法和测度法快速计算一般分形图形分形维数的程序，只能处理eVYBky格式和DhWqdHj的分形图形，运行效率高。 (This is a course designed MATLAB code, he is a use of scales and measurement method for rapid calculation of general fractal graphics fractal dimension of the program, can only handle eVYBky format and DhWqdHj fractal graphics, high operating efficiency. )

说明：  应用matlab语言编写图像处理函数,实现灰度直方图均衡化(Using MATLAB language to write image processing function to realize gray histogram equalization)

matlab仿真程序，产生QPSK调制的信号，严格按照QPSK的调制步骤分I路Q路产生信号，最后两路相加，产生已调信号，调制信号随机产生，载波信号是余弦信号。(matlab simulation program to produce the QPSK modulation signal, in strict accordance with the QPSK modulation of the sub-step road Q road I have a signal, the sum of the last two, have been transferred signal, randomly generated modulated signal, carrier signal is a cosine signal.)

谱分解（Spectral decomposition），是将矩阵分解为由其特征值和特征向量表示的矩阵之积的方法。(Spectral Decomposition , is the product of the matrix into the matrix method by eigenvalues and vector representation.)

Gaussian differential.
