the matlab book answersthe matlab book answers(the matlab book answers!the matlab book answers!the matlab book answers!)

说明：  本程序经过本人的调试运行，能够实现对手写数字的识别，成功率达 80(After I debug this program to run, to realize the handwritten digit recognition, the success rate of 80)

说明：  一个信号处理的的方法ICA，有用到的可以分享(ICA)

仿真锁相环系统，可以仿真锁定时间。不同的环路带宽对系统的非理想特性！(PLL simulation system that can lock simulation time. Different loop bandwidth of the system of non-ideal characteristics!)

实现维纳滤波器的设计，进过实践完全可行，请放心下载(Achieve Wiener filter design, into the practice entirely feasible, please rest assured download)

计算具有A=L*D*L 形式的Cholesky因式分解，适用于一些特殊矩阵。(Calculated with A = L* D* L ' forms of Cholesky factorization for some special matrices.)

matlab可用的HMM工具箱，包括DHMM，GHMM和混合HMM等(HMM toolbox matlab available, including DHMM, GHMM and hybrid HMM, etc.)

This script will attempt to find the band gaps in a phononic crystal by carrying out a Plane Wave Expansion of the various quantities It is for an acoustic wave equation with pressure instead of the displacement as prescribed in App. Phys. Lett. 70 3218 There are 3 programs, one for short, one for elastic long and the other one is for acoustic long(This script will attempt to find the band gaps in a phononic crystal by carrying out a Plane Wave Expansion of the various quantities It is for an acoustic wave equation with pressure instead of the displacement as prescribed in App. Phys.
