1 Minpack includes software for solving nonlinear equations and
2 nonlinear least squares problems. Five algorithmic paths each include
3 a core subroutine and an easy-to-use driver. The algorithms proceed
4 either from an analytic specification of the Jacobian matrix or
5 directly from the problem functions. The paths include facilities for
6 systems of equations with a banded Jacobian matrix, for least squares
7 problems with a large amount of data, and for checking the consistency
8 of the Jacobian matrix with the functions.
