北航數(shù)值分析2-二次插值與曲面擬合

1、數(shù)值分析 2015/12/61北京航空航天大學(xué)數(shù)值分析大作業(yè)姓名：郝海東學(xué)號(hào)：ZY1506227數(shù)值分析 2015/12/63結(jié)果輸出 void put(int k)? 數(shù)據(jù)結(jié)構(gòu)設(shè)計(jì)本例中未涉及到復(fù)雜數(shù)據(jù)結(jié)構(gòu)，(x,y,z)點(diǎn)集和非線性方程組 F’(X)采用二維矩陣存儲(chǔ)。在曲面擬合時(shí)，各種矩陣的存儲(chǔ)為一維數(shù)組，在進(jìn)行行列的轉(zhuǎn)換也較為方便。完整代碼（編譯環(huán)境 windows10 + visual studio2010）：// algo2.

2、cpp : 定義控制臺(tái)應(yīng)用程序的入口點(diǎn)。#include “stdafx.h“#include #include double iter[4][5];double point[7][7];double deltav,deltaw,deltax,deltay;double *c;#define print printf(“-----------------------------------------------------------

3、----------------------------------\n“);void init(){iter[0][0] = 1;iter[0][1] = 1;iter[0][2] = -1;iter[0][3] = 0;iter[1][0] = 1;iter[1][1] = 1;iter[1][2] = 0;iter[1][3] = -1;iter[2][0] = 0;iter[2][1] = 1;iter[2][2] = -1;i
