sci
Minpack includes software for solving nonlinear equations and
nonlinear least squares problems. Five algorithmic paths each
include a core subroutine and an easy-to-use driver. The algorithms
proceed either from an analytic specification of the Jacobian matrix
or directly from the problem functions. The paths include facilities
for systems of equations with a banded Jacobian matrix, for least
squares problems with a large amount of data, and for checking the
consistency of the Jacobian matrix with the functions.
This is the C re-write of the original fortran minpack
implementation.
