光子晶体波导非线性的程序！非线性系数和能量的关系曲线！(Nonlinear photonic crystal waveguide program! Non-linear coefficients and the energy curve!)

通信系统的仿真,卷积码是纠错码的一种,可以用于数字电视,手机等通信领域,本例子给出了基于matlab的程序，卷积码BPSK调制。(Simulation of communication systems, convolutional code is an error-correcting code can be used for digital television, mobile phones and other communications, the examples given based on the matlab program convolution code BPSK modulation.)

libsvm的最新函数包，包含了各种语言的接口，可方便的实现分类，回归等问题(libsvm package)

通常情况下是线性的分类,但在复杂情况下,要把他转换到另一空间来,以便线性的分类, SVM有其优势,还能做非线性的波束形成.(under normal circumstances is linear classification, but in complex situations, it is necessary to change his room to another, to the linear classification, SVM has its advantages, the ability to do nonlinear beam forming.)

此源码为进行手写文字识别的Matlab经典算法的实现，希望能对大家有所帮助(This source for handwritten character recognition algorithm of the Matlab classic realize the hope that it can be helpful to everyone)

希望对大家有所帮助，祝大家学习进步，有时间共同探讨问题 (Would like to help everyone, I wish everyone to learn and progress, have time to explore the issue of)

英文版书籍，关于matlab的入门基础，适合初学者(English books, the entry on the basis of matlab for beginners)
