C/C++ Minpack

====== readme for minpack ====== 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 directory contains the double-precision versions. Jorge More', Burt Garbow, and Ken Hillstrom at Argonne National Laboratory.
