*Abstract.*We introduce the notion of Parikh matrix induced by a word, a natural extension to the notion of Parikh matrix and prove a set of properties for this kind of matrices.We also study the relation between these two notions. We show that combining properties from both we obtain a more powerful tool for proving algebraic properties of words.
