Which program can you use to plot a 3-D surface: z=sin y cos x, x∈[0,2π], y∈[0,2π], in figure window?( )

A、x=0:pi/20:2*pi;[x,y]=meshgrid(x);z=sin(y).*cos(x);surf(x,y,z);;
B、x=0:pi/20:2*pi;[x,y]=meshgrid(x);z=sin(y).*cos(x);surface(x,y,z);gridon;view(-30,37.5);
C、fx=@(x,y)x;fy=@(x,y)y;fz=@(x,y)sin(y).*cos(x);fsurf(fx,fy,fz,[0,2*pi]);
D、fx=@(x,y)x;fy=@(x,y)y;fz=@(x,y)sin(y).*cos(x);surface(fx,fy,fz,[0,2*pi])
