php_calc
- 用PHP编写的表达式计算器，是用的编译的知识实现的，并非使用eval()函数实现。 功能强大，可以做所有的数值计算，代数计算还不能实现。 1。可以计算形如“-3*sin(2^0.5/2+3.1415)-pi()^2”的式子。 2。能识别数字（包括小数、正负数）、数学函数。 3。可以做加、减、乘、除、指数、取模 计算（其中加、减包括一元和二元两种操作）。 压缩包里的“math.php”是演示文件-with PHP prepared by the express
Matrix.operation
- 用户输入两个矩阵的维数和元素，选择加减乘三种运算方式中的一种，程序将显示运算结果。采用动态分配数组空间。初学C++写的，简单易懂。-user input two-dimensional matrix of elements and a few select modified by the three operators a way, Operational procedures will show results. Dynamic array allocation of space. Novic
pow
- double pow(double,double) 省去了libm的麻烦。可以自由使用-double pow (double, double) save a libm trouble. Free use
bin_to_dec
- 可转大量超长二进制为十进制，例如三千个64位二进制可在3秒内完成-may make substantial long binary to decimal, such as 3000 64 in binary completed within 3 seconds
LP--simplex
- lp求解的单纯形算法，有c++builder6.0开发-lp for the simplex algorithm, c builder6.0 Development
gpsweek
- 把年月日时分秒转换为GPＳ周，秒的程序！-put date when accurate conversion of GPS week, the procedure seconds!
LU_decompostion
- 矩阵的LU分解的改进型算法。优点是快捷-matrix factorization of the improved algorithm. Advantage is speed.
Waveleb
- 小波分解源代码，基于Scilab！Scilab是一个OpenSource的类似matlab的工具，通过该源代码可以为开发小波分析提供参考！-wavelet decomposition of the source code, based on SCILAB! SCILAB OpenSource is a similar Matlab tool adoption of the source code for the development of wavelet analysis provide a
