ndsu3lib is a Fortran library for calculation of SU(3)-SU(2)xU(1) reduced coupling coefficients, SU(3)-SO(3) reduced coupling 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.

A simple program ndsu3lib_example_cpp demonstrating usage of the C++wrappers is provided.

The following libraries are required:

• 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 coupling coefficients)

Download links and documentation for WIGXJPF and MPFUN2020-Fort can be found here:
