phi=0:0.01*pi:pi
for x=-2*pi:0.1*pi:2*pi
A(phi,x)=(2*besselj(1,x-1.92))/(x-1.92)+(2*besselj(1,x+1.92))*cos(phi)/(x+1.92);
B(phi,x)=(2*besselj(1,x+1.92))*sin(phi)/(x+1.92);
A1(phi)=real(A(phi,x));
A2(phi)=imag(A(phi,x));
B1(phi)=real(B(phi,x));
B2(phi)=imag(B(phi,x));
I(phi,x)=(A1(phi,x)-B2(phi,x))^2+(A2(phi,x)+B1(phi,x))^2;
UP(phi)=max(x-I(phi));
DOWN(phi)=min(x-I(phi));
V(phi)=(UP(phi)-DOWN(phi))/(UP(phi)+DOWN(phi));
end
plot(phi,V(phi));
想实现的是绘一个图，纵标为phi，横标为不同phi对应的V，请问程序该怎么改

phi=0:0.01*pi:pi ；
for x=-2*pi:0.04*pi:2*pi
A(phi,x)=(2*besselj(1,x-1.92))./(x-1.92)+(2*besselj(1,x+1.92)).*cos(phi)./(x+1.92);
B(phi,x)=(2*besselj(1,x+1.92)).*sin(phi)./(x+1.92);
A1(phi)=real(A(phi,x));
A2(phi)=imag(A(phi,x));
B1(phi)=real(B(phi,x));
B2(phi)=imag(B(phi,x));
I(phi,x)=(A1(phi,x)-B2(phi,x)).^2+(A2(phi,x)+B1(phi,x)).^2;
UP(phi)=max(x-I(phi));
DOWN(phi)=min(x-I(phi));
V(phi)=(UP(phi)-DOWN(phi))./(UP(phi)+DOWN(phi));
