We discuss the implementation of a novel demanding algorithm to compute contraction metrics for nonlinear systems. We compare MATLAB- and C++-implementations and study the effect of parallelizing the code. Further, we explore the use of different low-level math-libraries for the C++-implementation and the use of an undocumented code-path that considerably speeds up MATLAB code 011 AMD's Ryzen processors.

Abstract
We discuss the implementation of a novel demanding algorithm to compute contraction metrics for nonlinear systems. We compare MATLAB- and C++-implementations and study the effect of parallelizing the code. Further, we explore the use of different low-level math-libraries for the C++-implementation and the use of an undocumented code-path that considerably speeds up MATLAB code 011 AMD's Ryzen processors.
