Helo!
I have a matrix G(n,m) and I need to be able to convert it to a dxf file. I am having trouble extrapolating the values in the matrix and turning them into 3 matrices for each dimension x,y,z.

I want the value in the matrix to be dimension z and the rows/columns to be x and y respectively. basically, I want to convert the surf(..) of my matrix into it's components so that I can export them as a dxf file using the writedxf.m from paul seigle.

first I tried a double for loop to read in the data from the matrix, but then ran into trouble with referencing the rows outside the loops.

any ideas?
thanks much!

I almost wanted to write reshape() so that you can make 3D out of 2D a.v.v., but then I just looked what reshape really does... and start to wonder where in my codes I've been using it and if it did what I thought it did...

a = zeros(2,2,3); for ii = 1:3; a(:,:,ii) = [1,2;3,4]; end;
b = reshape(a, 6, 2, 1)
c = reshape(b, 3, 2, 2)

yep the problem is getting the values out of the matrix and still having hem correlate to the specific row/column they came from. I know one way is a double for loop, but I am having trouble finding a way to reference the new matrix for correct index numbering.
