Hi everyone.
I am trying to plot my data in 3D surface. However, it currently does not work since my X,Y, and Z are independent. Z is not F(X,Y). I also try to use meshgrid but still does not work. The reason that I want to plot surface because my scatter plot points are trade-off. Thus, if i can show it in surface, it will be easier to interpolate my trade-off. Do I have any other ways to use surf function?
Thank you very much.

What relationship is there between z and x and y? What is z? Is it a 2D matrix? Is it a vector? Is it a volumetric array, like a CT or MRI image?

t=0:0.01:2;
x=0:0.01:1;
surf(x,t,u1array);
does not work for u1array being 201x101 ?
That's surprising.
Best wishes
Torsten.

Thanks Torsten. My t and x arrays are very above my code and somehow it did not put the right axes limits. Now it is working. Thanks so much.
