短时傅里叶变换的例子，matlab语言,简洁实用(shot time Fourier transform using matlab)

说明：  讲解一些Matlab编程基础、Matlab的数据类型、MATLAB语言概述、矩阵和数组、图形基础内容(Learn some basic Matlab programming, Matlab data types, MATLAB language overview, matrix and array, based on the content of graphics)

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. )

用于学习matlab语言编程的PPT文档，里面含有编程源代码。(Matlab programming language for learning PPT document, which contains programming source code.)

很好的matlab 的显示程序啊 欢迎下载啊(Very good display procedures matlab download ah ah welcome)

matlab fir滤波器程序 是一个列子 可以参考一下(matlab fir filter program can refer to a Liezi)

格式：[huffcodes，氢，領 ，电子] = huffmancoding（磷，氮） ％输入：p是每个字母符号的概率 （如：对= [0.3 0.2 0.2 0.2 .06 .04]） n是一个整数，决定在每个帧的符号数量 （默认：n = 1时） ％输出：huffcodes：huffmancodes 答：源熵 甲肝：平均熵编码 电子邮件：科丁效率(format : [huffcodes,H,Hav,e]=huffmancoding(p,n) inputs: p is the probability of each alphabet symbol ( eg:p=[.3 .2 .2 .2 .06 .04] ) n is an integer that determines number of symbols at each frame (default:n=1) outputs: huffcodes: huffmancodes H: source entropy Hav: average entropy for coding e: codding efficiency )
