Hi,
I am new to R, and am trying to solve the following optimization problem:
This is a nonlinear least squares problem. I have a set of 3D voxels. All I
need is to find a least squares fit to this data. The data model actually
represent a cube-like structure, consisting of seven straight lines. The
lines have some intersections (and at this intersection both of the
participating lines end).
Please note that I need something (some routines, maybe) that works for 3D
voxels, and to which I can feed my problem directly (ie, not feeding the
line equations separately, but together, since I have some line intersection
constraints).
(In case you need more detailed description of the problem, please view the

You'd also find a model image there.)
Thanks for your patience! Any help would be greatly appreciated.
