    This attempts to improve upon the solution generated by account for numerical imprecisions. See numerical recipes for more information. It is assumed that solve has already been run on 'b' and 'x' at least once.
    
    Parameters:
    
    b - A matrix. Not modified.
    
    x - A matrix. Modified.
