using the magic time-step in 1D FDTD grid, implement a total-field/scattered-field wave-source.

基于FIsher线性判别的两类模式分类器(Two kinds of pattern classifier based on Fisher linear discriminant )

This is a comprehensive guide to engineering students for using matlab

用斜率的方法来求时间序列的lyapunov exponent,在非线性动力学和时间序列处理中经常用到。很实用的小程序。(slope of the methods used to the time series for the lyapunov exponent. Nonlinear Dynamics and the time sequence processing frequently used. Very small practical procedures.)

计算Gabor特征的MATLAB代码，方便修改和计算。(MATLAB code for calculation of Gabor features for easy modification and calculation.)

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(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, decoding, MAP decoding algorithm using modified)

混凝土的抗压强度随养护时间的延长而增加，现将一批混凝土作成12个试块，记录了养护日期x（日）及抗压强度y（kg/cm2）的数据：求型回归方程 示例方程在内(The compressive strength of concrete with curing time and increase the extension, now make a number of concrete block 12, recording the date of the conservation of x (day) and compressive strength of y (kg/cm2) of data: the regression equation for sample-based equation, including)
