C/C++ Heart monitor sample application

三次样条插值的源程序，程序稍稍长了点 希望大家能用到(cubic spline interpolation of the source, procedures slight hope everyone can wait to)

这是一个比较有用的小程序，能对被水印出理过的图象进行检测，效果很明显．(This is a relatively small program useful, can be a watermark image over the rationale for testing, the effect is obvious.)

关于求解线性规划单纯形法的matlab程序 (Simplex method of linear programming in matlab program)

本函数将完成对输入的二维信号进行多尺度离散小波分解(This function will complete the two-dimensional signal input multi-scale wavelet decomposition)

改进cholesky分解，在cholesky分解基础之上进行改进，不需要分解的矩阵正定条件(Improve the cholesky decomposition, cholesky decomposition in the basis for improvement, positive definite matrix conditions without decomposition)
