Notes 
Sparse bundle adjustment problem from Mehdi Mazaheri, University of Calgary   
                                                                              
A is symmetric positive definite, coming from bundle adjustment of 1700 images
to optimize the trajectory of a multi-camera data acqusition system. The      
trajectory is a loop inside a building at the University of Calgary.
