how to plot create z-matrix from x,y,z cordinates

Hi, I'm just new to Matlab. I wish to plot the surface contour plot with the x, y, z coordinate having 1024 values. could anyone help me out with it .....

If your ‘x, y, z coordinate having 1024 values’ are already 2D matrices of the same size, each with 1024 elements, you can generate a surface and contour plot with:

surfc(x, y, z)

hi, I tried with surfc(x,y,z); but the error persisted as the surface Z must contain more than one row or column. In my workspace it showed as x= 1024x1, y=1024x1, z=1024x1. Now how could I solve out this error...

It depends on how your data are organised. Even though they’re vectors, they could actually be gridded.

I would plot your data as:

stem3(x, y, z)

to see what your data look like. If they appear to be gridded, you may only need to reshape the vectors into matrices to use the surf function.
