一个用matlab编写的基于的指纹匹配程序，可以下载来看看，希望对你有所帮助。(Written by matlab a fingerprint-based matching procedure, you can download to see, you want to help.)

To calculate the coupling partitial difference equation of heat transition and diffusion.

基于MATLAB 的语音信号频谱分析与去噪研究 1、通过Matlab读入语音信号，进行频域分析 2、绘制语音信号频谱； 3、设计滤波器并进行滤波； 4、加噪，对比语音信号波形和频谱(Research on speech signal spectrum analysis and denoising based on MATLAB 1, read the voice signal through Matlab and analyze it in frequency domain. 2, draw the frequency spectrum of speech signal; 3. The filter is designed and filtered. 4. Add noise and compare the waveform and spectrum of speech signal)

说明：  其中含有人工蜂群算法的源代码和各种测试函数的源代码，可运行蜂群算法 matlab(It contains source code of artificial bee colony algorithm and source code of various test functions, which can run bee colony algorithm)

matlab下实现降噪，功率谱计算。％程序中设定采样点数为256个，采样频率为10000hz， ％输入信号为随机噪声和两个正弦的合成信号 ％设定的滤波器的截止频率为3500hz ％通过挈比雪肤滤波器，运行程序，比较滤波前后的频域波形 ％滤波去除了高频信号(matlab achieve noise reduction, power spectrum calculation. Sampling procedure set for 256 points, the sampling frequency of 10000hz, input signal for the random noise and the two sinusoidal signals synthetic filter set a cut-off frequency 3500hz manner than through the filter雪肤, run procedures, compared before and after filtering in frequency domain waveforms filtering in addition to high-frequency signals)
