- Newton-Raphson's method can handle non-linear n-dimensional equations
- with reasonable results given a good starting point. What happens
- if the system of equations is over-determined ? i.e. M equations in
- N unknowns where M > N.
-
- I used the routine mnewt() from Numerical Recipes ... with SVD as the
- backbone linear equation solver. It always converged when M <= N but
- refused to converge when M > N.
-
- Any comments about this ? Can NR handle M > N at all or does the
- algorithm have to modified to make it work ?
