相似性计算

用CORDIC算法实现的2参数反正切。结果的精度与CORDIC的迭代次数有关，迭代次数越多，精度越高。本例子中精确到小数点后4位。要提高迭代次数，还得把增加1QN格式的位数，比如32位long，程序多处需要修改，有需要的话自己改吧。 -CORDIC algorithm with the two parameters arc tangent. And the accuracy of the CORDIC iteration number, the more the number of iteration, the higher the accuracy. This case accurate to four decimal places. To raise the number of iterations, it has to the increase in a 2:30 format of the median, such as 32 long, multiple procedures need to change, the need to reform it themselves.

编写程序用牛顿迭代法求解下面的非线性方程组：例如 x1 = 0.7 sin(x1) + 0.2 cos(x2); x2 = 0.7 cos(x1)- 0.2 sin(x2);

《陈必红算法》一书的附带的源代码，并有经本人修改过能在VC中使用。原书是在C++BUILDER中使用的。并加了一些其他的功能，比如样条插值等。此代码，可以完成矩阵的很多数值算法，求逆阵、特征向量、特征值，矩阵的加减乘除、傅立叶变换、gamma函数、数值解分微分等。-"Chen Hung method," a fringe of the source code, and as I changed the VC can be used. The original book is in the C BUILDER used. Plus a number of other functions, such as spline interpolation. This code can be completed in many numerical matrix algorithm, the inverse matrix, the eigenvectors and eigenvalues, the matrix arithmetic. Fourier transform, gamma function, numerical solution of differential- such.

基于DFT的频谱细化程序

这是一个支持多位数运算（可以达到几百位的长整数）的数类，名字叫Long，它是从long类发展过来的，但比原来的long类功能多。Long类可以和原有的double，long等等数据类型混合运算-This is a multi-digit support operations (which may reach hundreds of long integers) to a number of named Long, it is long from over the type of development, but more than the original multi-functional long. Long classes can be double the original, long data types, etc. Operational mixed

这是一个利用VC++编写的求逆矩阵的算法，在WindowsXP、2000、98上运行成功。-This is a VC prepared by the inverse matrix algorithm, in WindowsXP, 2000,98 running successfully.
