MATLAB: Converting RGB surf plot to stl file for 3D printing

Question

I'm currently writing a script that takes a 2d image and turns it into a 3d stl file for 3D printing. So far I have: im = imread(filename); size(im)

im_red = im(:,:,1); size(im_red)

h=surf(double(im_red))

From here Matlab plots the image according to RGB data, which creates a 3D image. I would like to take this surf plot and convert it into an stl file.

Thank you!

You can download some STL file conversion tools from FEX:
