自己写的几个matlab的函数，自己处理数据是常用。有滤波函数、平移函数等。处理后新生成的数组和原数组大小相同，行列特性也相同。(Himself wrote several matlab functions, deal with their own data is commonly used. There are filtering function, translation function, and so on. The new array is generated after treatment and the original array the same size, the ranks of features are the same.)

Matlab中erf(x)函数的表达式是怎样的，erf(x)与标准正态分布函数之间的关系是怎样的，怎样自己编制一个计算标准正态分布函数数值近似值的函数，如何利用matlab自带的erf(x)函数包近似计算标准正态分布函数的值，数值计算值与用erf(x)转化求得的值之间的相对误差是怎样的。(将中文译成英语 Matlab, erf (x) function expression is what, erf (x) the standard normal distribution function and the relationship between what and how to prepare their own calculation of the standard normal distribution function a value function approximation, how to use matlab comes with erf (x) function package approximate standard normal distribution function values??, numerical values ??and with erf (x) between the values ??obtained into the relative error is like. )

使用matlab语言编程解决非线性规划问题(Using matlab language programming to solve nonlinear programming problems)

一本很好的matlab实现的最优化的电子书。(Matlab achieve a good optimization eBook.)

JSONArray的使用 附带程序注释与输出(JSONArray use with program notes and output)

蛙跳算法,包含Flow_Shop_Scheduling_Problem、 Function_Optimization、 Knapsack_Problem、 Traveling_Salesman_Problem(flog leap algorithm, including Flow_Shop_Scheduling_Problem, Function_Optimization, Knapsack_Problem, Traveling_Salesman_Problem)

2个不同调制方式的MATLAB仿真程序，是QPSK和QAM的，都非常好(Two different modulation of the MATLAB simulation program is QPSK and QAM, are very good)

this is source code about extracting cars number

简短的MATLAB语言，求出以V为水平初速度的物体下降弹道曲线方程及速度方程。以水平方向和竖直方向分解。(Short MATLAB, to find the initial velocity V as the level of objects down ballistic curve equation and rate equation. Horizontal and the vertical decomposition.)

DTW（Dynamic Time Warping，动态时间归整）算法，该算法基于动态规划（DP）的思想，解决了发音长短不一的模板匹配问题，是语音识别中出现较早、较为经典的一种算法。(DTW (Dynamic Time Warping, Dynamic Time Warping) algorithm based on dynamic programming (DP) ideas, to solve the pronunciation of different lengths of the template matching problem, is the speech recognition appeared in the early, more of a classical algorithm.)
