A non-linear least squares solver that is primarily developed by the Numerical Analysis group at STFC Rutherford Appleton Laboratory [email protected].
RALFit has been tested on Linux, although it should work on other platforms. It requires Fortran and C compilers, and BLAS and LAPACK must be installed on the system
To compile, move to the libRALFit directory and issue the commands:
mkdir build
cd build
cmake ..
make
The package is written in modern Fortran, and we provide a number of interfaces for other languages. For documentation, follow the links below:
