levmar 0.2.3

Python binding to the levmar library using Cython.

A Python binding to the levmar library. Note that this is a fork of https://github.com/tkanmae/levmar.

Description

The levmar is GPL’ed ANSI C implementation of the Levenberg-Marquardt (LM) optimization algorithm. The LM algorithm provides a numerical solution to the problem of minimizing a function over a parameter space of a function. The levmar library provides implementation of both unconstrained and constrained LM algorithms (box, linear equation, and linear inequality constraints).

Installation

Simplest way to install levmar and its dependencies is to use the conda package manager:

$ conda install -c bjodah levmar pytest
$ python -m pytest --pyargs levmar  # runs the test-suite

alternatively you may also use pip:

$ python -m pip install --user --upgrade pytest levmar
$ python -m pytest --pyargs levmar

you can skip the --user flag if you have got root permissions.
