Surface area of a 3D-plot from a matrix.

Hi guys. I'm trying to calculate the area of a surface. My problem is something like this:
I have some images in 8bits ... something like this one:
I made a Java program so I can turn those images into a matrix and open it with MatLab.
When I run my program for this image it returns me something like this:
matrix = [255,255,255,255,255;
Then I can put this matrix in matlab and use the function surf. So I get something like this:
Now comes my problem. Is there any way to calculate the surface area of this 3d-plot? Can be anything that returns me a quantitative value for this surface area.
ps: sorry for my english, im from Brazil.
