Hello,
I have two row-vectors, A (1X8000) and B (1X8000). What I want is their surface plot. I tried the commands below:
surf(A,B)
colorbar
But it does not work. The following error occurs.
Error using surf
Z must be a matrix, not a scalar or vector.
How can the surface plot of the two variables be made? Your help is valuable.

Depending on what your data represents, there could be different ways to do it. One of the ways possible is this:
M = [A; B]';
surf(M);

You cannot do that. surf() and surface() can only handle 2D grids of data. For surf() and surface() the X and Y data do not need to be rectangular or even rectilinear -- you can even use them to plot a hemi-sphere for example -- but they do need to be 2D.
If you had three vectors instead of two vectors, you could consider using tools such as griddata or scatteredInterpolant
