the programs are an introduction to DSP ,the programs illustrate the frequency response ,impulse response and magnitude response

matlab 数字图像信号的频域分析及仿真 将二维数字图像进行傅立叶频域分析，并且做了图像幅度谱重建和相位谱重建，通过这个例子大家可以明白相位比振幅更重要。(matlab digital image signals in frequency domain analysis and simulation of two-dimensional digital image Fourier frequency domain analysis, and has done a reconstruction of the image amplitude spectrum and phase spectrum reconstruction, by this example we can understand the phase is more important than the amplitude.)

说明：  遗传算法用于求函数最大值，可以修改函数名和迭代次数(A function of genetic algorithm is used to seek the maximum, you can modify the function name and the number of iterations)

用CHM格式罗列了常用的MATLAB函数，便于在一时无法想起时，迅速查找函数(CHM format with a list of commonly used MATLAB functions, easy to remember the moment when you can not quickly find the function)

The kernel-ica package is a Matlab program that implements the Kernel ICA algorithm for independent component analysis (ICA). The Kernel ICA algorithm is based on the minimization of a contrast function based on kernel ideas. A contrast function measures the statistical dependence between components, thus when applied to estimated components and minimized over possible demixing matrices, components that are as independent as possible are found.

说明：  用FFT做谱分析的实验代码，附有详细的实验说明和源代码以及对实验现象的分析(FFT spectrum analysis done using the experimental code, with detailed experimental descriptions and source code as well as the analysis of experimental phenomena)
