SPLASH is a c++ class library that implements many of the Perl constructs and data types, including extensive regex regular expression pattern matching. For those not familiar with Perl, it is an excellent scripting language by Larry Wall and is available for most platforms. This Class library provi ...

一个命令行运算器源代码
用C++写的命令行运算器，支持加、减、乘、除、乘方和小括号（可嵌套），乘方的符号是^^，因为在WINDOWS的命令行模式下^是一个连接符。
用法：cal expression
expression = expression op expression
expression = (expression)
op = + | - | * | / | ^^ ...

Knowledge of the process noise covariance matrix
is essential for the application of Kalman filtering. However,
it is usually a difficult task to obtain an explicit expression of
for large time varying systems. This paper looks at an adaptive
Kalman filter method for dynamic harmonic state estimatio ...

Text processing often involves matching text against a pattern. Although Java s character and assorted string classes offerlow- levelpattern- matching support, that support commonly leads to complex code. To help you write simplerpattern- matching code, Java provides regular expressions. After intro ...

UC Library Extensions
UnderC comes with a pocket implementation of the standard C++ libraries, which is a reasonably faithful subset. This documentation describes those UnderC functions and classes which are not part of the C++ standard.

Builtin functions:
Most of these are standard C ...

Implement the step 2 of two-level logic minimization. Our goal is to find the minimum (exact
minimum) sum-of-products expression for a given function.

We address the problem of blind carrier frequency-offset (CFO) estimation in quadrature amplitude modulation,
phase-shift keying, and pulse amplitude modulation
communications systems.We study the performance of a standard
CFO estimate, which consists of first raising the received signal to
the Mth ...

数据结构 表达式类型的实现: 1、 一个表达式和一颗二叉树之间
表达式类型的实现:
1、 一个表达式和一颗二叉树之间，存在着自然的对应关系。
2、 假设算术表达式Expression内可以含有变量（a～z）、常量（0～9）和二元运算符（＋，－，*，/，^）。实现一下操作。
（1） ReadExpr(E)——以字符序列的形式输入语法正确的前缀表示式并构造表达式E。
（2） WritrExpr(E)——用带括弧的中缀表 ...
并行计算 本计算器实现了如下两个功能： 1、windows自带计算器的键盘输入加减乘除
本计算器实现了如下两个功能： 1、windows自带计算器的键盘输入加减乘除，目前没有连续运算功能操作：用户用键盘或者鼠标分别输入‘1’，‘＋’，‘2’，按‘＝’ 文本框显示运算结果‘3’。 2、表达式运算功能，目前只支持整数运算。操作：选择菜单Option->Expression，在文本框用键盘输入表达式如‘12/2+(4*5/4)*6’，按 ...
