说明：  在学习数字信号处理算法程序中用VC编写的几个通用算法程序。 卷积计算/DFT与FFT实现/(In the learning process of digital signal processing algorithms using VC General Algorithm for the preparation of several procedures. Convolution calculation/DFT and FFT realization /)

C++中矩阵运算的实现 nr3.h为其他的书籍代码，测试环境为VS2008(Achieve C++ in matrix operations nr3 code for other books)

基于热焓法的凝固传热模拟的UFluent-UDF程序(UDF for Modelling Soldification using Enthalpy Porosity Technique)

LDL分解法，用于求解大型的线性方程组。此程序中最多能解100维的，速度还不错(LDL decomposition method for solving large-scale linear equations. This procedure can be up to 100 peacekeepers solutions, speed is not bad.)

这是非均匀B样条曲线构造方法代码，如果有问题可以邮件联系：wuxiaod1987@163.com(NUBUS Spline Build)

fft code in visual c++

fluent关于蒸发相变的很全的C程序，有详细的注释，对于相关专业的人很重要(fluent the evaporation phase transition is full C program, detailed notes, very important for the people of the relevant professional)

最小二乘法拟合曲线C++代码，任意的M个数据，任意的次数N(N不易太高)。输出拟合曲线的表达式(Least Squre For ...)

说明：  给定四个数（1--13），判经过四则运算后能否得到结果24，若能，输出表达式。 (Given the number four (1- 13), after sub after four computing results can be 24, if the output expression.)

说明：  这是LU分解法求线性方程组的资料，讲解了LU分解的原理及过程，非常实用(LU decomposition seeking linear equations to explain the principles and process of the LU decomposition, very practical)
