整理的一些delphi 开发中中经常用到一些函数-Finishing some delphi development of a number of frequently used function

function [tout, yout] = rk4(ypfun, tspan, y0, h) ％定步长四阶Runge-Kutta法求常微分方程(组)数值解 ％[tout,yout] = rk4( ypfun , tspan, y0,h) ％ 这里字符串ypfun是用以表示f(t, y)的M文件名, ％ tspan=[t0, tfinal]表示自变量初值t0和终值tf ％ y0表示初值向量y0，h是步长。 ％ 输出列向量tout表示节点 (t0 , t1 , … , tn) ％ 输出矩阵yout 表示数值解，每一列对应y的一个分量-function [tout, yout] = rk4 (ypfun. tspan, y0, h)% fixed step four-stage Runge- Kutta method for ordinary differential equations (Group) numerical solution% [tout. yout] = rk4 (ypfun, tspan, y0, h)% string ypfun here is used to indicate that f (t, y) M name, tspan% = [t0. tfinal] said variable initial and final t0 tf% y0 said initial vector y0, h is a step. % Output column vector tout said Node (t0, t1, ..., tn)% output matrix yout said numerical solution, each y counterparts out of a weight

清理vc编译后的中间文件，vc60下编译。是你保持不必要的资源浪费！-Clean-up between vc compiled documents, vc60 compiler under. Is that you keep unnecessary waste of resources!

for： Root of a Polynomial --- --- --- --- -- Time Limit: 1 Second Memory Limit: 32768 KB -------------------------------------------------------------------------------- A polynomial of degree n has the common form as . Your task is to write a function to find a root of a given polynomial in a given interval. Format of function double Polynomial_Root(int n, double c[], double a, double b, double EPS) where int n is the degree of the polynomial double c[] is an array of n +1 coefficients , , ..., , and of the given polynomial double a and b are the two end-points of the given interval and double EPS is the accuracy of the root. The function must return the root. Note: It is guaranteed that a unique real number r exists in the given interval such that p(r) = 0. -for: Root of a Polynomial---------------------- Time Limit: 1 Second Memory Limit: 32768 KB-------------------------------------------------------------------------------- A polynomi
