In this demo, I use the EM algorithm with a Rauch-Tung-Striebel smoother and an M step, which I ve recently derived, to train a two-layer perceptron, so as to classify medical data (kindly provided by Steve Roberts and Will Penny from EE, Imperial College). The data and simulations are described in: ...

该程序为matlab环境下程序，主要演示“科学与艺术奇才”皮克欧沃的国王映射(King map)，可以生成许多类似三维的复杂曲面，调整参数，或者加上高阶摄动项，会得到更多的花样一个

This LDPC software is intended as an introduction to LDPC codes computer based simulation. The pseudo-random irregular low density parity check matrix is based on Radford M. Neal’s programs collection, which can be found in [1]. While Neal’s collection is well documented, in my opinion, C source c ...

本程序是一个行计算器（即对表达式求值）。计算器能实现加、减、乘、除、取余（％）和乘方（^）运算；能实现三角函数（正弦函数sin和余弦函数cos），求10为底的对数log，求2为底的对数ln，求e的指数幂exp，其参数也可以是合法的表达式； 计算器并能对表达式的合法性进行测试，错误的能给出表达式错误的信息。 ] 输入文件格 ...

包含附件中的头文件，就可以在出log时，将log写到文件中，方便调试。

msLinux v1.0 可以在arm ads 下仿真运行的linux，对学习linux很有帮助 运行于ARMulate时，请选择在ARMulate目录下的map文件

用VHTL描述7段数码管器，输入为一个四位二进制，在数码管上显示数字的同时也显示这四位二进制。使用了port map语句

C++STL STL（Standard Template Library，标准模板库)是惠普实验室开发的一系列软件的统称。它是由Alexander Stepanov、Meng Lee和David R Musser在惠普实验室工作时所开发出来的。现在虽说它主要出现在C++中，但在被引入C++之前该技术就已经存在了很长的一段时间。 STL的代码从广义上讲分为三类：algorithm（算法）、cont ...
