Beta Release: 11/13/92 This directory contains the 1992 version of the MINPACK-2 test problem collection. Included in the software are nonlinear least squares problems, systems of nonlinear equations, and minimization problems. Both single and double precision versions of the test problems are available. Subroutines are named by the following convention: The first letter in each subroutine name dictates arithmetic precision, s for single, d for double. The second thru fifth letters describe the application, eg. fic denotes the flow in a channel problem. The sixth and seventh letters denote the subroutine action. letters 6 and 7 action --------------- ------ fj function, Jacobian, initial approximation js Jacobian times vector fg function, gradient, initial approximation hs Hessian times vector sp Jacobian sparsity structure bc Boundary data Please report any comments and errors to: Jorge J.
