this program compare the Locally Weighted Linear Regression with three diferrent kernel function (gaussian, logistic basis, and Reciprocal Multiquadric) also compare locally weighted by simple Linear Regression.

说明：  对信号类型的说明，并画出其相应的波形，求出信号的功率和能量。(Description of the type of signal, and draw the corresponding waveform, find the power and energy of the signal.)

自己写的关于弹载SAR的源程序，对初学者非常有用！(Write your own source code on missile-borne SAR, and very useful for beginners!)

psk modulation is done using simulink model in this document. hope u get knowledge

Design A Root-Raised Cosine Filter

这个Matlab程序实现最速下降算法。最速下降法是一种最基本的算法，它在最优化方法中占有重要地位.最速下降法的优点是工作量小，存储变量较少,初始点要求不高；缺点是收敛慢，最速下降法适用于寻优过程的前期迭代或作为间插步骤，当接近极值点时，宜选用别种收敛快的算法. (Matlab implementation of this procedure steepest descent algorithm.)

这是一篇关于如何运用超图的理论经过办监督学习用在特征选择上的一篇ecml文章(This is an article on how to use the hypergraph theory after office supervised learning with a ecml articles feature selection)

RobustICA和FastICA算法功能一样，但比FastICA更稳定更简单，包含演示程序，简单易用(RobustICA has the same function as FastICA,but is more stable and easier,including demo programme,it s easy to use.)
