C/C++ Minpack

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.

• version 1.3.8 (09/02/2021):

  • CMake now builds by default the single-, double-, and extended-precision versions #45 #48
  • Avoid promoting to doubles in all operations for the single-precision version #47

• version 1.3.7 (09/12/2020):

  • Makefile cleanups #11
  • Cmake-related fixes #20 #21 #23 #27 #28
  • Add Appveyor CI #24
  • Add support for single-precision CBLAS and LAPACK #40

• version 1.3.6 (24/02/2017):

  • Fix FreeBSD build #6
  • CMake: install CMinpackConfig.cmake rather than FindCMinpack.cmake #8
  • CMake: add option USE_BLAS to compile with blas #9

• version 1.3.5 (28/05/2016):

  • Add support for compiling a long double version (Makefile only).
  • CMake: static libraries now have the suffix _s.

• version 1.3.4 (28/05/2014):

  • Add FindCMinpack.cmake cmake module. If you use the cmake install, finding CMinpack from your CMakeLists.txt is as easy as find_package(CMinpack).

• 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 -C fortran, then make -C examples and follow the instructions). Added driver tests lmsdrv, chkdrv, hyjdrv, hybdrv. make -C examples alltest 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 -C cuda (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 -DBUILD_SHARED_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
