I wrote this program for coloring any map with only 4 colors. Input for it is an bitmap file with 24 bit colors (must gray/scale). Output is a bitmap which is colored with maximum 4 colors.

基于FFT平面相控阵天线方向图快速计算 (Figure quickly calculate FFT-based planar phased array antenna direction)

进行时域分析的好程序，刚和师兄编的，仅供参考(Good time domain analysis procedures, and senior compiled just for reference only)

维纳滤波Matlab代码 1 可以直接作为函数调用； 2 可以减少图像的块效应，以及平滑图像。(Wiener Filter Matlab code can be used directly as a function call 2 blocks can reduce the image effects, and smoother image.)

本文提出了一种基于独立分量分析的音频数字水印方法。嵌入水印时,对原始音频文件进行一级小波分解,在分解 得到的逼近分量中利用随机混合方法嵌入水印后进行小波逆变换形成嵌入水印的音频文件。仿真实验结果表明这种方 法的强鲁棒性和可行性。(Abstract:Audio p roduction is one of the important digital multimedias, which transmit becomes more and more convenient. To p revent the multimedia content from being stolen or illegally used, audio content p rotection techniques become increasingly impor2 tant so that the potential of these app lications can be reached. As the importantmethod of copyright p rotection, the digitalwater2 marking technology has been acquired widely recognition and research. This paper p resents a method of digital audio watermark2 ing based on independent component analysis. When embedding watermarking, the original audio is decomposed by single2level discrete 12D wavelet transform, watermarking is embedded by mixing randomly to the app roximation coefficient vector obtained, and the audio is single2level reconstructed receiving audio havingwatermarking. Emulated experiment results show that thismeth2 od is robust and feasible.)

matlab计算排列熵的程序,可以定量分析混沌或噪声序列的复杂度(a program that is capable of computing the permatation entropy of a time series noise or chaos waveform.)

用龙贝格法求定积分，此例的变量数为三，但整体思路是没错的。(With Romberg method for the definite integral, the number of variables in this case is three, but the overall idea is correct.)
