C++ 線性插值

函數功能：輸入兩個值，指定插值后數組長度，輸出線性插值后的數組。

void test(double a, double b){ 2     cout << "section: " << a << " " << b << endl; 3     const int INSERTPOINTNUMBER = 10; 4     double c[INSERTPOINTNUMBER] = {0.0}; 5     for(int i = 0; i < INSERTPOINTNUMBER; ++i){ 6         c[i] = (a * (INSERTPOINTNUMBER - i) + b * i) / float(INSERTPOINTNUMBER); 7         cout << c[i] << endl; 8  } 9 }
