这是书籍:Matlab控制系统与应用的源码,(This is the book: Matlab control system and application source code,)

its used for speech recognition

Speech analysis in matlab

说明：  智能控制仿真GUI界面，对离散化的受控对象进行不同方式的控制（包括传统PID控制、模糊PID控制、神经PID控制和专家及仿人智能控制），然后通过分析不同条件下的单位阶跃响应指标，比较各控制方式之间的差异及控制特点。(intelligent control GUI)

当信噪比低，小信号输入时噪音严重，在整个音域的声音明显变得浑浊不清，不知发的是什么音，严重影响音质。信噪比的大小是用有用信号功率（或电压）和噪声功率（或电压）比值的对数来表示的。(When the signal to noise ratio is low, serious small signal input noise, the sound of the entire range becomes significantly turbid, I do not know what made the sound, seriously affecting the sound quality. Size is the number of the signal to noise ratio by the ratio of desired signal power (or voltage) and the noise power (or voltage) represented.)

本程序为非负矩阵分解，matlab程序。输入为要分解的矩阵和端元数，输出为分解的结果(this program is suitable for NMF .the input data is the matrix to be decomposed and the number of endmember.output is the result)

拓扑优化程序 拓扑优化程序，研究生课程机械优化设计的课程大作业(Topology optimization program topology optimization program, postgraduate courses mechanical optimization design big job)

FSK雷达原理简述，详细分析了测距和测速的原理过程。。。FSK雷达原理简述，详细分析了测距和测速的原理过程。(Principle of FSK radar, range and velocity are analyzed in detail the principle of the process.)
