Dear all, I will appreciate any ideas how to create a surface object from a complex data as follows:

    x=0:10:200;

    t=0:0.2:2;

surf(x,t,real(u));

or

surf(x,t,imag(u));

or

surf(x,t,abs(u));

or

surf(x,t,real(u));
hold on
surf(x,t,imag(u));

There are other possibilities, but you need to describe your thinking about what you would like the display to be considering the 2D nature of complex values.
