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)

稀疏脉冲反褶积代码,包括高尔消元法解矩阵方程阻,自相关,互相关,褶积,反褶积的代码. 刚参加工作那会儿,上进心也足,爱动脑,编了很多的程序,唯有这一个是我引以为傲的,花了几个星期写的稀疏脉冲(预测)反褶积的代码,放到了现在,觉得也没必要再私藏下去了,不出五年,我都不知道这段代码是干什么的了. 希望对大家有用,方法太简单,所以效果不是太好,请大家修改,如要转载,请记得注明出处. (vc++)
