ROC计算方法,最大似然估计方法计算曲线的ROC(Maximum Likelihood Estimation of a Binormal ROC Curve)

说明：  实现小波数字水印，比较简单 采用量化数组嵌入(The realization of wavelet digital watermarking, is relatively simple to quantify the use of embedded array)

一个emd分解程序，包括瞬时频率，瞬时幅值，边际谱，Hilbert谱(A emd decomposition process, including instantaneous frequency, instantaneous amplitude, the marginal spectrum, Hilbert spectrum)

该程序是基于Kalman Filter 理论编写的基本的Matlab 滤波程序！(This code is relative with the basic Kalman Filter.)

周期对称方波信号的傅里叶级数展开 有限项级数来逼近无限项级数(fourier series )

PCDMIS电极检测方案,可以自动搜寻基准12个点的位置，并计算出电极坐标(PCDMIS electrode detection scheme that can automatically search for the location of the base 12 points and calculate the coordinates of the electrodes)

一个带案例对比的S-G滤波,红色为处理结果，绿色为无噪信号，蓝色为含噪信号(A S-G filter with case comparison)

说明：  由于matlab提供了一些很有用的计算方法 但是大部分用户只用到其中一部分的功能 所以写了一个包括解方程，矩阵计算，排序功能的代码(As matlab provides some very useful method but most users only use part of the function it was a including solving equations, matrices, and sorting code)

这是姜启源教授在清华大学讲解数学建模课程的资料，对于数学建模由入门到精通十分有用(lecture in math modeling,given by Professor JiangQiyuan )

数值分析中基于Matlab环境下的关于最小二乘的源代码(Numerical analysis environment based on Matlab source code on least-squares)
