Yes, computational ease... and speed.
Speaking of speed, attached is a zip file containing a test case of N and d for the normal equations Nx=d.
Would you please solve it for x using Octave and tell me how long it takes? (Don't include the time it takes to read the large N matrix from the disk, just the computation time).
PS:
N and d were created from the official qual Match Results posted by FIRST for 75 regional and district events plus MAR, MSC, Archi, Curie, Galileo, & Newton. So solving for x is solving for World OPR.
