一种PSK的调制方式 ，提供初学者参考，挺好的资料，参考(tihs is a programe of psk module way ,it can help you fing that you will like it)

说明：  MATLAB高级编程,MATLAB工程数学,MATLAB实用教程,MATLAB图形图像等源码集锦(MATLAB high-level programming, engineering MATLAB mathematics, MATLAB practical guides, such as MATLAB graphics source Collection)

本程序用mathematics开发的弹簧摆小程序，简单易行，可以很好的调节不同状态的弹簧摆 (This procedure mathematics developed spring pendulum with a small program, simple and easy to adjust the different states can be very good spring pendulum)

模拟滤波器，实现模拟信号的FIR滤波，并画出单边频谱图(Analog filters, analog signal FIR filter, and draw the unilateral spectrogram)

采用matlab编写，对图像椒盐噪声与周期性噪声的进行滤除(Using matlab, image noise and periodic noise salt and pepper to filter out)

双峰法是一种简单的阈值分割方法，即如果灰度级直方图呈现明显的双峰状，则选双峰之间的谷底所对应的灰度级作为阈值分割。(Two peaks is a simple threshold segmentation method, that is, if the gray level histogram showed a clear bimodal shape, then choose between the two peaks corresponding to the bottom of the gray level as threshold segmentation.)

支持向量机工具，可以在matlab下运行(support vector machine tools, can run under Matlab)

亚式期权和欧式期权的一篮子组合以及策略测试(Asian options and European options on a basket of portfolio and strategy testing)

用于计算离散信号的很不错的matlab样本熵程序(Very good for computing discrete signal matlab sample entropy program)

偏最小二乘法是集主成分分析、典型相关分析和多元线性回归分析3种分析方法的优点于一身(PLS is a principal component analysis, canonical correlation analysis and multiple linear regression analysis three kinds of analysis method has the advantage in a)
