matlab code for convolutional codes

数字水印图像的攻击测试 包括滤波、剪切、添加噪声、jepg压缩攻击等等(Attack test digital watermarking images, including filtering, cropping, adding noise, jepg compression attack, etc.)

SIMULATION USING MATLAB AND SIMULINK

This is an efficient implementation of PCA, which use smaller dimension of the data matrix to compute the eigenvectors

matlab电机仿真50例，电机仿真必备教材，你值得拥有。(matlab simulation of 50 cases of motor, motor simulation necessary materials, you deserve to have.)

C——C方法计算，用于相空间重构分析，很好很使用的一种方法(C- C method for phase space reconstruction analysis。It is ery good and useful。)

This example shows the use of the FFT function for spectral analysis. A common use of FFT s is to find the frequency components of a signal buried in a noisy time domain signal.

随机数演示程序，可以产生均匀分布，正态分布和瑞利分布的随机数，并画图表示。(Random Number demo program can generate uniformly distributed random lognormal distribution and rayleigh, and drawing representation.)
