Also available are the up-to-date versions of NL2SOL (TOMS algorithm | |
573): n2f and n2g correspond to NL2SNO and NL2SOL; | |
n2p is a variant of NL2SOL that allows the residual vector | |
and Jacobian matrix to be passed in pieces, rather than all at once; | |
n2[fgp]b are versions of NL2SOL that handle simple bounds; | |
ns[fg] are versions for separable nonlinear least-squares, and | |
ns[fg]b are versions for separable nonlinear least-squares with | |
simple bounds. dn[s2][fgp][b ] are the double-precision versions. | |
Similarly available are current versions of SMSNO, SUMSL, HUMSL (TOMS | |
algorithm 611) for general unconstrained minimization: | |
mnf uses function values only; | |
mng uses function and gradient values; | |
mnh uses function, gradient, and Hessian values; | |
mn[fgh]b are versions that handle simple bounds; | |
dmn[fgh][b ] are double-precision versions. | |
