将cell类型的数据转换为double类型的函数(Converts the data of type cell to a function of type double)

本程序设计的是咬尾编码的turbo码，用matlab编写。咬尾turbo码也即不需要拖尾比特，使得前后两个状态相同，译码采用修正的MAP译码算法。此文件为咬尾编码矩阵生成的测试文件包(This program is designed to encode the turbo tail biting code, written with matlab. Tail biting turbo code that is not trailing bits to make the same before and after the two states, the MAP decoding using modified decoding algorithm. This file is biting the end of the generated test code matrix package)

shrodinger solving with matlab

画出每个IMF分量及最后一个剩余分量residual的图形 画出每个IMF分量及剩余分量residual的幅频曲线 用Hilbert变换直接求该信号的瞬时频率 计算HHT时频谱和边际谱(Draw each IMF component and the last one remaining residual component graphics draw each IMF component and the amplitude of the remaining component of the residual frequency curve directly seeking the instantaneous frequency of the signal with the Hilbert transform spectrum and marginal spectrum calculation HHT)

说明：  function [ret,x0,str,ts,xts]=s3(t,x,u,flag) s3 is the M-file description of the SIMULINK system named s3. The block-diagram can be displayed by typing: s3. SYS=s3(T,X,U,FLAG) returns depending on FLAG certain system values given time point, T, current state vector, X, and input vector, U. FLAG is used to indicate the type of output to be returned in SYS.

sd method for optimum design

FDTD程序关于一维时域有限差分法（分层介质，反射，透过系数-FFT）(1-D FDTD code with simple radiation boundary conditions)

很不错的ofdm仿真程序，改程序会使你对正交频分复用有较深的理解(OFDM is a good simulation program, changing the procedure would you OFDM has a better understanding of)

说明：  用matlab实现图像角度旋转代码，可以实现图像的任意角度旋转(Angle of image rotation using matlab code, can achieve any angle image rotation)

说明：  matlab的mapminmax函数（投影映射），在使用libsvm中没有它总是报错~~(The mapminmax matlab function (projection map), in the use of libsvm not it always error ~ ~)
