ndsu3lib is a Fortran library for evaluation of SU(3)-SU(2)xU(1) reduced Wigner coefficients, SU(3)-SO(3) reduced Wigner coefficients and SU(3) recoupling coefficients, namely U, Z and 9-(lambda,mu) coefficients.
A simple program ndsu3lib_example demonstrating usage of the library is provided.
C++ wrappers of Fortran subroutines are provided. The C++ functions are in the file ndsu3lib.h along with interface documentation.
The following libraries must be installed:
- Lapack (unless recoupling coefficients are not going to be calculated)
- WIGXJPF or GNU Scientific Library (unless only SU(3)-SU(2)xU(1) reduced Wigner coefficients are going to be calculated)
- optionally MPFUN2020-Fort (recommended for SU(3)-SO(3) reduced Wigner coefficients)
Download links and documentation for WIGXJPF and MPFUN2020-Fort can be found here:

The Variant 2 of MPFUN2020-Fort is used, therefore use the script gnu-complib2.scr (if using gfortan) or intel-complib2.scr (if using ifort).
