基于Scilab的粒子群算法代码，Scilab是一个功能和matlab差不多的开源软件(Based on the Particle Swarm Optimization Scilab code, Scilab is a functional and open source software similar to matlab)

基于matlab的计算机数值法设计平面型微带传输线：带状线阻抗计算、微带线阻抗计算、损耗计算(Computer numerical methods matlab design based on planar microstrip transmission line: stripline impedance calculation, microstrip line impedance calculation, calculation of losses)

1.将BMP图像内容读入内存数组。 2. 调整图像的灰度，对图像进行灰度变换（反变换）。 3. 对图像进行较正,分别取值为0.4,0.6,0.8.(1. The BMP image content is read into memory array. 2 Adjust the gray image, the image gray-scale transformation (inverse transform). 3 more positive image, respectively, the value of 0.4,0.6,0.8.)

说明：  代码是基于Matlab的图像融合算法性能测试，可以对各种融合算法进行分析并且看出各种算法融合效果的优劣(Matlab code is based on performance tests of image fusion algorithms that can analyze a variety of fusion and fusion to see the pros and cons of various algorithms)

说明：  利用matlab实现的聚类的一些源码，大家可以(Using matlab to achieve some of the cluster source, we can)

all image processing toolboxes

基于FrFT的时变幅度LFM信号参数估计，采用二维峰值搜索算法，后用一维曲线拟合，大大减少了计算量。(The parameter estimation of LFM signal based on FrFT is based on two dimensional peak search algorithm and one dimension curve fitting, which greatly reduces the computation.)

系统辨识用，用来辨识非线性系统的参数，还可以对非线性系统进行仿真。(System identification, used to identify nonlinear system parameters, it can also nonlinear system simulation. )

最大似然估计算法Matlab实现，不容易啊！！！！！！！！！！(Maximum likelihood estimate，not so esay！！！！！！！！！！)

正交频分复用的调制的实现代码，调制只用一种方式(Orthogonal frequency division multiplexing modulation implementation of the code modulation only way to)
