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 package provides the headers, man pages, examples, and static library.
