| tmean | A 3x1 vector, local translation from n1 to n2 |
| qpmean | A Quaternion, local rotation from n1 to n2 |
| prec | A 6x6 matrix, precision matrix for this link |
- Returns
- true if constraint added, false if nd0 or nd1 not found

do LM solution for system; returns number of iterations on finish. Argument is max number of iterations to perform, initial diagonal augmentation, and sparse form of Cholesky.
Run the LM algorithm that computes a nonlinear SPA estimate. <niter> is the max number of iterations to perform; returns the number actually performed. <lambda> is the diagonal augmentation for LM. <useCSparse> is true for sparse Cholesky. 2 for gradient system, 3 for block jacobian PCG <initTol> is the initial tolerance for CG <maxCGiters> is max # of iterations in BPCG
