使用指针或函数声明数组

问题描述

#include <iostream>
using namespace std;
int main()
{
    Vectorf point(3);
    point.set(0,0,3.0);
    point.set(1,0,2.0);
    point.set(2,0,1.0);

    double angle = 0.0;
    float sx = 0.5, sy = 0.5;
    float ax = 2.0, ay = 2.0;
    float tx = 0.0, ty = 1.0;
    double const Pi = 4 * atan(1.0);
    angle = Pi / 6 ;
    cout<< "The result of Rotation (angle).Skew(s).Scaling(a).
Translation(t) X M of point is(M'') " << endl <<
        (Rotate_R(Skew_s_X(Skew_s_Y(Scale_a(Translate_t(point,tx,ty),ax,ay),sx),sy),angle));
    cout << endl;
    return 0;
}

我必须将矩阵M={{''3''},{''2''},{''1''}};乘以
(Rotate_R(Skew_s_X(Skew_s_Y(Scale_a(Translate_t(point,tx,ty),ax,ay),sx),sy),angle));
如何声明矩阵并将其乘以上述函数... ???

解决方案

#include <iostream>
using namespace std;
int main()
{
    Vectorf point(3);
    point.set(0,0,3.0);
    point.set(1,0,2.0);
    point.set(2,0,1.0);

    double angle = 0.0;
    float sx = 0.5, sy = 0.5;
    float ax = 2.0, ay = 2.0;
    float tx = 0.0, ty = 1.0;
    double const Pi = 4 * atan(1.0);
    angle = Pi / 6 ;
    cout<< "The result of Rotation (angle).Skew(s).Scaling(a).
Translation(t) X M of point is(M'') " << endl <<
        (Rotate_R(Skew_s_X(Skew_s_Y(Scale_a(Translate_t(point,tx,ty),ax,ay),sx),sy),angle));
    cout << endl;
    return 0;
}

i have to multiply a matrix M={{''3''},{''2''},{''1''}}; to
(Rotate_R(Skew_s_X(Skew_s_Y(Scale_a(Translate_t(point,tx,ty),ax,ay),sx),sy),angle));
how to declare a matrix and multiply it to the above thing...???
