LSFODF: A Generalized Nonlinear Least-Squares Fitting Program for Use with ORELA ODF Files

摘要

The Fortran-10 program LSFODF has been written on the ORELA PDP-10 in order to perform non-linear least-squares curve fitting with user supplied functions and derivatives on data which can be read directly from ORELA-data-format (ODF) files. LSFODF can be used with any user supplied function and derivatives; has its storage requirements specified in this function; has P-search and eta-search capabilities; and can output the input data and fitted curve in an ODF file which then can be manipulated and plotted with the existing ORELA library of ODF programs. A description of the fitting formalism, input instructions, five test cases, and a program listing are given. (ERA citation 04:022957)
