WebNov 17, 2001 · Unlike the later LINPACK and LAPACK libraries, which encode the argument precision in routine names, MINPACK uses the same names for single- and double-precision versions of each routine. It is thus imperative to pick one precision or the other, and then select the load library accordingly.

"WebI need to implement a non-linear fitting algorithm in Fortran and chose to use MINPACK's flavor of the Levenberg-Marquardt algorithm as a basis for the least-squares stuff. However, I seem to misunderstand something very basic about how these routines are to be used. My understanding is that I have to call the routine lmdif1 and define a ... " - Fortran minpack
