Model DBPSK signal with AWGN channal

采用Bfgs算法解决光滑的半监督支持向量机，并采用不同的光滑函数进行比较(Using Bfgs algorithm to solve the smooth semi-supervised support vector machines, and using smooth function to compare different)

用于检测提取特征点的可重复性代码，可重复性好则说明特征较好(for detection feature extraction point code of repeatability, reproducibility is better to describe characteristics)

使用CAV方法求解病态方程组，得出较为精确的解，(Using the CAV method for solving equations ill, arrive at a more accurate solution,)

牛顿插值，前插共识，前插公式，用matlab实现数值计算方法中的牛顿向前插值公式。(newton_interpolation)

the blind signal detection using the various length of the LSCMA algorithm

说明：  详述了Matlab中contour画图的命令及技巧，针对出现的问题进行了说明和逐一演示。(Matlab detailed contour drawing of the orders and skills, for the problems described, and each presentation.)

it read an ascii file, cut the signal, organize in a matrix, and the output will be a .mat or .txt file.

说明：  在2d不光滑曲面上的射线跟踪算法，效果比较好，希望可以帮助到大家(2d surface is not smooth in the ray-tracing algorithm, the effect is good, hope you can help to)
