图像水平变换：分别实现对图像的水平外凹和水平外凸。(Image level of transformation: the implementation level of the image and level .)

This is a code of Pseudo-Arc Length Continuation Method , the method can be used for solving the nonlinear equations, the principle can re found in some text books. In the code,I prove the agreement of the code with other methods

用firgr函数设计的两种类型的FIR低通滤波器，( minorder/minodd )边界频率fre_edge=[0 .345 .575 1]*pi 显示幅频特性(Firgr function design with two types of FIR low-pass filter, (' minorder/minodd' ) boundary frequency fre_edge = [0 .345 .575 1]* pi shows the amplitude frequency characteristics)

用MATLAB对图形图像处理，实现无码掩盖(Image processing using MATLAB graphics, cover-free code)

matlab implementation for forward-backward algorithm for train and test of hidden markov model (HMM).

该源码用于分析信号的时频特性，wigner-ville分布，单信号以及两个信号间的正交wigner-ville分布(wigner-ville distribution)

说明：  认知场景下加性高斯噪声对于误码的影响，已经干扰问题的转换源码(Cognitive scenarios for the additive error of Gaussian noise has been the conversion source interference problem)

The program purikura.m frames your images into a beautiful frame. Convert your boring looking images into decorated ones using it. Automatically adjusts the bordering i.e. framing according to the image s dimensions. Save the decorated images.(The program purikura.m frames your images into a beautiful frame. Convert your boring loo king images into decorated ones using it. Autom atically adjusts the bordering i.e. framing ac cording to the image's dimensions. Save the deco rated images.)

用来生成任意长度的m序列，需要输入初始值和本原多项式的系数(M used to generate the sequence of any length, you need to enter the initial value and the primitive polynomial coefficients)

matlab图像处理应用，利用matlab进行图像处理的书籍(application of imaging processing in matlab)
