说明：  这是基于生物学中实际神经元动作电位产生机制而建立的神经元发火模型。(This is based on the actual biological neurons mechanism of action potentials and the establishment of neurons ignition model.)

说明：  使用步频信号生成距离像，包含变量频率步数，频率差，散射体数量，距离元，散射体移动速度，来生成散射体的距离像。(Step-frequency signal generated using the range image that contains the variable frequency step, frequency difference, the number of scattering from the element, scattering body speed, to generate the scattering of Range.)

PNM Toolbox，用于Matlab的各种各样对图像处理的源码库(PNM Toolbox for Matlab variety of image processing code libraries)

Linear Regression with multiple variable

Image Compression A collection of simple routines for image compression using different techniques. BTCODE: Image compression Using Block Truncation Coding. PYRAMID: Image compression based on Gaussian Pyramids. DCTCOMPR: Image compression based on Discrete Cosine Transform. IMCOMPR: Image compression based on Singular Value Decomposition. The given codes can be also used in 2D noise suppression. Notes: The function conv2fft performs a 2D FFT-based convolution. Type help conv2fft on MATLAB command window for more informations.

实现对激光自混合干涉的仿真，对各个参数的仿真都可以实现。但性能不是很好。(Laser self-mixing interference simulation, simulation of the various parameters can be achieved. But the performance is not very good.)

数字通信调制信号模拟系统:MASK：2ASK，4ASK，8ASK MPSK：2PSK、4PSK、8PSK MFSK：2FSK、4FSK、8FSK 分连续相位CPFSK和离散相位DPFSK两种 MQAM：16QAM、32QAM、64QAM、128QAM OFDM：子载波数可任意选定，映射方式有BPSK、QPSK、4QAM、16QAM、32QAM、64QAM (Digital communication modulation signal simulation system: MASK: 2ASK, 4ASK, 8ASK MPSK: 2PSK 4PSK 8PSK MFSK: 2FSK 4FSK 8FSK continuous phase the of CPFSK and the discrete phase DPFSK both MQAM: 16QAM, 32QAM, 64QAM, 128QAM OFDM: sub- carriers can be arbitrarily selected, and mapping methods are BPSK, QPSK, 4QAM, 16QAM, 32QAM, 64QAM)

本MATLAB是用来提取语音信号的MFCC特征，可对.wav文件进行特征提取(The MATLAB is used to extract the MFCC features of speech signals,.Wav files can be extracted)
