FLENS (Flexible Library for Efficient Numerical Solutions) is a linear algebra library written in C++ that provides matrix and vector types as templates and wraps BLAS/LAPACK routines so they can be called with C++ syntax. Its distinguishing feature is that it supports notation close to mathematical formulas through operator overloading while preserving performance by delegating computation to external BLAS implementations such as OpenBLAS. It was developed at Ulm University in Germany.
