很不错的NMF代码！里面对NMF做了一个非常巧妙的非负限制.(NMF code is very good! NMF done inside of a very clever non-negative constraints.)

It is Simulink model for Double-sideband transmitter.

Sutton :An Introduction:Reinforcement Learning全书所有章节代码(Sutton :An Introduction:Reinforcement Learning，all chapter all codes)

this is a code for at89c5131 usb supprt micro. this code shows communication protocols to of USB in micro. this code can be used by at89c5131 and use Matlab USB code which I uploadto communicate Simulink of Matlab to a micro via USB.Enjoy it!

ISAR 成像时利用多普勒中心法进行相位补偿的matlab程序(Doppler phase compasation)

基于传输矩阵法（TMM）计算VCSOA（垂直腔半导体光放大器）的稳态增益的程序。由于是从将输入端功率Pin作为已知条件，程序用Matlab优化工具箱中的fsolve函数计算了满足边界条件时的输出功率。这对于相关研究开发都是较好的资料。(This is a set of source codes, which are used for calculating the steady state gain of VCSOA based on the transfer matrix method(TMM). Since the input power of the VCSOA is regarded as a already-known condition, this program, the function "fsolve" in the Matlab Optimization Toolbox is used for obtaining the output power of the VCSOA when the input power is at some value. This is a good material for further studying the related problems, especially when using the Matlab for device simulations. )
