Matlab下单字语音识别程序。Readme.txt中有使用方法的详细说明。(Vocabulary speech recognition under the program Matlab. Readme.txt in detail using the method.)

说明：  计算长方形产生的重力异常,理论计算和具体的实现方法.(Calculation of gravity anomaly caused by rectangle)

选择一张灰度图像和一张彩色图像，经过matlab仿真后能够将彩色图像上的颜色转移到灰度图像上！！！(Select a gray image and a color image, through the matlab simulation, the color images can be transferred to the gray color of the image! ! !)

useful matlab codes for beginners

说明：  神经网络BP辨识的Matlab算法，用于辨别复杂的非线性系统(Identification of the Matlab neural network BP algorithm, used to identify the complex nonlinear systems)

基于论文“滑模变结构控制DC_DC变换器的设计”的matlab程序仿真(Based on the sliding mode variable structure control for DC_DC converter matlab simulation program design)

说明：  实现短时傅里叶变换，真的挺好用的，大家可以十四看看呀(TFRSTFT this is a program ,you can try it in you computer)

This program performs the max-flow algorithm

说明：  基于矢量量化的说话人识别系统,可以实时录音检测(VQ speaker recognition system can detect real-time recording)

说明：  最近看到有人提问怎样用FFT实现频谱分析，我认为能够进行到频谱分析的人，对于系统研究的深度基本上已经相当不错了。本人今天做了一个例程，发给大家参考一下。 历程主要内容(signal_analyzer.rar)如下： test1.txt 第一列为时间t，0.001s为步长；第二列为系统的输入信号；第三列为系统的输出信号。 signal_analyzer.m首先将test1.txt 的数据读入workspace，然后进行FFT，分析出两信号的频率，输出对于输入的幅值衰减（db），输出对输入的相位差。(The question was asked recently to see the realization of how to use FFT spectral analysis, I think that spectral analysis can be carried out to those who study the depth of the system basically is already quite good. Today I made a routine, distributed to Members for reference. The main contents of the course (signal_analyzer.rar) are as follows: test1.txt the first time as t, 0.001s for the step the second as the system input signal the third as a system output signal. signal_analyzer.m first test1.txt data read into workspace, and then proceed to FFT, analysis of the two signal frequency, output amplitude for input attenuation (db), the output of the input phase difference.)
