C++ 中的反斜杠

Question

在 Matlab 中 x=A\b；求解线性系统 Ax=b。是否可以在 C++ 中模仿相同的内容？可以使用运算符重载，但如何在以下程序中使用 \ 而不是 /？

friend Vector operator/(const Vector &b, const Matrix &A)
{   //BiCG Algorithm is used here. 
    int row=A.getrowdim();
    int col=A.getcoldim();
    Vector x(row,0.0);
    Vector r(row,0.0);
    Vector s(row,0.0);
    Vector u(row,0.0);
    Vector v(row,0.0);
    Vector w(row,0.0);
    Vector p(row,0.0);
    double rho0,beta,alpha,rho;
    Vector t(row,0.0);
    double norm;
    r=b-A*x;
    s=r;
    rho0=1;
    for(int k=1;k<M;k++)
    {
        rho=s*r;
        beta=rho/rho0;
        u=r+beta*u;
        w=s+beta*w;
        v=A*u;
        alpha=rho/(w*v);
        x=x+alpha*u;
        r=r-alpha*v;
        s=s-alpha*(Transpose(A)*w);
        norm=r.norm(2);
        cout<<"Step Number "<<k<<" xnorm "<<norm<<endl;
        if(norm<eps)
            break;
        rho0=rho;
    }
       return x;
}

Answer 1

没有

你不能重载operator\（主要是因为它不存在）。

像任何其他函数一样，为操作起一个漂亮、清晰、描述性的名称。
