作业帮这个matlab怎么画投影图或者是等高线图?程序是 figurefor x1=0:0.05:3 for x2=-2:0.05:0 wp=-0.9375*x1; wp1=0.9375*(2-0.5-2*x1)*(0.5+1)*(x2)^2; plot3(x1,x2,wp1-wp,'m.');hold on endendcontourgrid

这个matlab怎么画投影图或者是等高线图?
程序是
figure
for x1=0:0.05:3
for x2=-2:0.05:0
wp=-0.9375*x1;
wp1=0.9375*(2-0.5-2*x1)*(0.5+1)*(x2)^2;
plot3(x1,x2,wp1-wp,'m.');hold on
end
end
contour
grid on
xlabel('\beta');ylabel('\wp_2');zlabel('\Re')
