聂善和1228用MATLAB标记复平面上方程的根对应的点集合我想用MATLAB画出ax^2+bx+c=0(a b c 属于 - 4到+4的整数)再复数范围内的根对应的点集合 -
沈皇南17855985469 ______[答案] i=1; for a=-4:1:4 for b=-4:1:4 for c=-4:1:4 if a==0 if b==0 continue else x(i)=-c/b; y(i)=0; i=i+1; end else if b^2-4*a*c>=0 x(i)=(sqrt(b^2-4*a*c)-b)/2/a; y(i)=0; x(i+1)=(-sqrt(b^2-4*a*c)-b)/2/a; y(i+1)=0; else x(i)=-b/2/a; y(i)=sqrt(4*a*c-b^2)/2/a; x(i+1)=-b/2/a; y(i+1)...
