GM(1,1)模型 MATLAB(matlab)

用三次样条曲线进行精密星历插值和卫星钟差插值(Cubic spline curve the precise ephemeris interpolation and satellite clock error interpolation)

细化骨架的简单程序，对二值图进行操作，如果对于空洞比较大的，先进行膨胀操作(Refinement of skeleton simple program, if the hole bigger, to expand operations )

This is is matlab m file to calculate am,gm,rms, hm

matlab codes for kernel SVM

本文件是DTMF信号采用卷积法进行解码的源程序，可以解码到DTMF信号的原始频率。(This document is a DTMF signal is decoded by convolution of the source, you can decode the DTMF signal to the original frequency.)

说明：  】利用混沌动力学系统中logistic 映射先对水印图像进行置乱预处理以增强其鲁棒性, 在小波域中将原始音频信号按比例分段, 此比例为原始音频信号低频部分与水印信号个数之比, 然后将水印信号加入到音频信号的 低频部分。用StirMark 攻击后的实验结果表明, 该算法对StirMark 的部分攻击具有一定的鲁棒性。(The logistic- map sequences to encrypt the watermark are used. The original audio signal in DWT (Discrete Wavelet Transform) domain is seperated into some pieces determined by the ratio between the length of the low frequency parts and the length of the encrypted watermark. Every bit of the watermark is added into the relevant pieces of the low frequency parts in the DWT domain. Experimental results show that the algorithm is robust against some StirMark attacks.)

turbo码的C程序，许多行前面都有些序号 请自己更正以后运行(turbo code of C procedures, many firms are some of the serial number in front of your own running after correction)

说明：  从最基本的问题入手，循序渐进，逐渐过渡到较为复杂的数学问题、信号分析问题、力学问题和电 学问题的求解，将MATLAB的学习贯穿在解决不同领域实际问题的过程当中(Starting from the fundamental issue, step by step, gradually transition to more complex mathematical problems, signal issues, mechanical issues and electrical problem solving, learning through the MATLAB to solve practical problems in different areas of the process of)

说明：  k均值算法，用matlab实现的，数据挖掘(k-means)
