Topography plot
in [Matlab]
|
From: adam Smith on 15 Jul 2010 08:15 I am trying to generate a topography plot of a surface. The surface consists of 4 squares where the elevation within each square is different. I want to visualize these elevations using a colormap. Any ideas???

If that doesn't suit your needs, then explain in more detail.

Well what I really need is the following. I will try to be as detailed as possible. I need to define the coordinates of 4 squares which are stacked along side each other; 2 in the horizontal direction and 2 in vertical direction or if you will 2 x 2 squares which are adjacent to each other. The height of the squares in z-direction is the same for all squares. However I want to visualize that a separate type of foundation is utilized within each square, which you could associate with different granular sizes. This I would want to visualize with different colors, for instance square one would have granular size = 1, square two would have granular size = 2 and so forth. I looked at the surf command and it seems to be able to do something along the lines of what I am looking for. I just don't know how to use it to define the square and how i would "color code" each square within its boundaries. Can you help me out with writing a simple code that would do this? Thanks
