此为本人matlab学习笔记，从入门开始，手把手教你学会(the matlab self study)

产生2fsk或4fsk的调制信号，可以控制带宽，中心频率，噪声，可以观察频谱(this can product signal)

一副图可视为一个矩阵，将其分成上线两部分，然后用矩阵的合并实现两个图简单拼接。目的主要使新手熟悉matlab的这种图形处理方法。(A diagram can be regarded as a matrix, to be divided into on-line in two parts, and then use the matrix of the merger of two diagrams simple splicing. The main purpose of the novice familiar with Matlab this graphical approach.)

说明：  声呐拖曳阵信号处理程序matlab程序包(Matlab package of signal processing program for sonar towed array)

Particle swarm optimization algorithm ( 粒子群优化算法)

灰色模型的几个源代码，给新手使用吧，里面包含了xcdxgm11.m；verhust.m；gm11.m；ccgm11.m四个文件(Several source code of the gray model, to use for novice)

基于灰色关联系数的模糊层次分析法。两种方法的综合运用，MATLAB编写，方便实用。(Correlation coefficient based on the fuzzy gray level analysis. Comprehensive use of the two methods, MATLAB prepared, convenient and practical.)

基于L型线阵的信号频率，方位角，俯仰角联合估计，采用MUSIC(Based on the L-linear array of signal frequency, azimuth, pitch angle joint estimation using MUSIC)

程序首先是编写2个输入，1个输出的隶属度函数；接下来的是模糊规则，一共49条；然后用解模糊函数得出控制量U，解模糊用到得规则是取隶属度最大的那个数即MOM算法。(The program first is to write two inputs, one output membership function next is fuzzy rules, a total of 49 then come to control the amount of ambiguity function U, ambiguity was used to take the membership rules are the biggest that number that MOM algorithms.)
