A Toolkit for Parikh Matrices

The Parikh matrix mapping is a concept that provides information on the number of occurrences of certain (scattered) subwords in a word. Although Parikh matrices have been thoroughly studied, many of their basic properties remain open. In the present paper, we describe a toolkit that has been developed to support research in this field. Its functionality includes elementary and advanced operations related to Parikh matrices and the recently introduced variants of P-Parikh matrices and L-Parikh matrices.
