这是一个用matlab语言编写的小波变换的程序，是时频分析的一种，可以在时域和频域内对信号进行分析。(using Matlab language of the wavelet transform procedure is time-frequency analysis of a kind in the time domain and frequency domain analysis of the signal.)

Z-Chirp Transfor Matlab Code

ldpc码matlab实现，恩，应该很好吧(ldpc matlab)

对一幅图像实现不同角度的旋转，从而可以观察不同角度的结果。( rotate_image- rotates an image given inside a matrix by the amount of "degree" counter-clockwise using linear interpolation of the output grid points from the back-rotated input points in this way, the output image will never have a "blank" point)

说明：  为了减少边缘检测中的噪声影响,设计了一种分数阶差分滤波器,给出了该滤波器的原理,分析了此类滤波器的幅频特性.(In order to reduce the effect of the noise in edge detection,a kind of fractional-order difference filters were designed,whose theory was worked out and amplitude-frequency characteristic were analyzed.)
