KMEANS
This directory contains code implementing the K-means algorithm. Source code
may be found in KMEANS.CPP. Sample data isfound in KM2.DAT. The KMEANS
program accepts input consisting of vectors and calculates the given
number of cluster centers using the K-means algorithm. Output is
directed to the screen.
Usage for KMEANS is:
KMEANS SOURCEFILE <enter>
The format of the source file is:
NPat - Number of patterns (int)
SizeVect - Size of vector (int)
NClust - Number of cluster centers(int)
vect[1,1] ... vect[1,SizeVect] - vector 1 (real)
vect[2,1] ... vect[2,SizeVect] - vector 2 (real)

Orthogonal Polynomials Approximation
数值分析，计算正交基多项式的系数
(Given a function f and a set of m >0 distinct points . You are supposed to write a function to approximate f by an orthogonal polynomial using the exact function values at the given m points with a weight assigned to each point . The total error must be no larger than a given tolerance.
Format of function
int OPA( double (*f)(double t), int m, double x[], double w[], double c[], double*eps )
where the function pointer double (*f)(double t) defines the function f int m is the number of points double x[] contains points double w[] contains the values of a weight function at the given points x[] double c[] contains the coefficients of the approximation polynomial double*eps is passed into the function as the tolerance for the error, and is supposed to be returned as the value of error. The function OPA is supposed to return the degree of the approximation polynomial.
Note: a constant Max_n is defined so that if the total error is still not small enough when n = Ma)

比Windows自带的高级一点的计算器，能将整个表达式输入，然后求值。
这个程序要求读者具备编译原理的一些知识。
(Advanced calculator than Windows built, the whole expression input can be then evaluated. This program requires the reader to have some knowledge of compiler theory.)
