How to combine two 1D functions into 3D plot?
显示 更早的评论
As the title says, I have a z(x) function and a z(y) function, they are both 1D functions. But I wanna show these 1D functions at the same scene, however, one is about x-axis, the other one is about y-axis, therefore, it should be a 3D plot when they wanna show at the same plot. My code as below:
x = linspace(-1,1,513);
y = linspace(-1,1,513);
[X,Y] = meshgrid(x,y);
Z0 = 625*sinc(25*x)-200*sinc(20*x).*exp(-1i*5*pi*x);
plot3(x,Y,real(Z0),'b')
hold on
Z90 = 625*sinc(25*y) - 50*sinc(5*y).*cos(10*pi*y);
plot3(Y,x,real(Z90),'r')
And I have also attached the plot I want, but I cannot make it, below comment is the figure I wanna get

surf(X,Y,real(Z0))
hold on
surf(X,Y,real(Z90))
shading interp

Thank you for your answer! But I cannot get the result like the plot shows in the question, I only get this

Use shading interp after surf

Hi KSSV, sorry to forget the shading interp, but i get the result like below, it is not desired though.
