C/C++ Minpack [](https://travis-ci.org/devernay/cminpack)
==========
This is a C version of the minpack minimization package.
It has been derived from the fortran code using f2c and
some limited manual editing. Note that you need to link
against libf2c to use this version of minpack. Extern "C"
linkage permits the package routines to be called from C++.
Check ftp://netlib.bell-labs.com/netlib/f2c for the latest
f2c version. For general minpack info and test programs, see
the accompanying readme.txt and http://www.netlib.org/minpack/.
Type `make` to compile and `make install` to install in /usr/local
or modify the makefile to suit your needs.
This software has been tested on a RedHat 7.3 Linux machine -
usual 'use at your own risk' warnings apply.

History
------
* version 1.3.3 (04/02/2014)::
- Add documentation and examples abouts how to add box constraints to the variables.
- continuous integration https://travis-ci.org/devernay/cminpack
* version 1.3.2 (27/10/2013):
- Minor change in the CMake build: also set SOVERSION.
* version 1.3.1 (02/10/2013):
- Fix CUDA examples compilation, and remove non-free files.
* version 1.3.0 (09/06/2012):
- Optionally use LAPACK and CBLAS in lmpar, qrfac, and qrsolv. Added
"make lapack" to build the LAPACK-based cminpack and "make
checklapack" to test it (results of the test may depend on the
underlying LAPACK and BLAS implementations).
On 64-bits architectures, the preprocessor symbol __LP64__ must be
defined (see cminpackP.h) if the LAPACK library uses the LP64
interface (i.e. 32-bits integer, vhereas the ILP interface uses 64
bits integers).
* version 1.2.2 (16/05/2012):
- Update Makefiles and documentation (see "Using CMinpack" above) for
easier building and testing.
* version 1.2.1 (15/05/2012):
- The library can now be built as double, float or half
versions. Standard tests in the "examples" directory can now be
lauched using "make check" (to run common tests, including against
the float version), "make checkhalf" (to test the half version) and
"make checkfail" (to run all the tests, even those that fail).
* version 1.2.0 (14/05/2012):
- Added original FORTRAN sources for better testing (type "make" in
directory fortran, then "make" in examples and follow the
instructions). Added driver tests lmsdrv, chkdrv, hyjdrv,
hybdrv. Typing "make alltest" in the examples directory will run all
possible test combinations (make sure you have gfortran installed).
* version 1.1.5 (04/05/2012):
- cminpack now works in CUDA, thanks to Jordi Bataller Mascarell, type
"make" in the "cuda" subdir (be careful, though: this is a
straightforward port from C, and each problem is solved using a
single thread). cminpack can now also be compiled with
single-precision floating point computation (define
__cminpack_real__ to float when compiling and using the
library). Fix cmake support for CMINPACK_LIB_INSTALL_DIR. Update the
reference files for tests.
* version 1.1.4 (30/10/2011):
- Translated all the Levenberg-Marquardt code (lmder, lmdif, lmstr,
lmder1, lmdif1, lmstr1, lmpar, qrfac, qrsolv, fdjac2, chkder) to use
C-style indices.
* version 1.1.3 (16/03/2011):
- Minor fix: Change non-standard strnstr() to strstr() in
genf77tests.c.
* version 1.1.2 (07/01/2011):
- Fix Windows DLL building (David Graeff) and document covar in
cminpack.h.
* version 1.1.1 (04/12/2010):
- Complete rewrite of the C functions (without trailing underscore in
the function name). Using the original FORTRAN code, the original
algorithms structure was recovered, and many goto's were converted
to if...then...else. The code should now be both more readable and
easier to optimize, both for humans and for compilers. Added lmddrv
and lmfdrv test drivers, which test a lot of difficult functions
(these functions are explained in Testing Unconstrained Optimization
Software by Moré et al.). Also added the pkg-config files to the
cmake build, as well as an "uninstall" target, contributed by
Geoffrey Biggs.
* version 1.0.4 (18/10/2010):
- Support for shared library building using CMake, thanks to Goeffrey
Biggs and Radu Bogdan Rusu from Willow Garage. Shared libraries can be
enabled using cmake options, as in;
cmake -DUSE_FPIC=ON -DSHARED_LIBS=ON -DBUILD_EXAMPLES=OFF path_to_sources
* version 1.0.3 (18/03/2010):
- Added CMake support.
- XCode build is now Universal.
- Added tfdjac2_ and tfdjac2c examples, which test the accuracy of a
finite-differences approximation of the Jacobian.
- Bug fix in tlmstr1 (signaled by Thomas Capricelli).
* version 1.0.2 (27/02/2009):
- Added Xcode and Visual Studio project files
* version 1.0.1 (17/12/2007):
- bug fix in covar() and covar_(), the computation of tolr caused a
segfault (signaled by Timo Hartmann).
* version 1.0.0 (24/04/2007):
- Added fortran and C examples
- Added documentation from Debian man pages
- Wrote pure C version
- Added covar() and covar_(), and use it in tlmdef/tlmdif
