Resumen

The elementary operations on matrices are of great importance and utility since they are applied in obtaining the so-called equivalent matrices, which are related to each other in many important attributes. In this paper we describe a new package for dealing with the elementary matrix operations of a given matrix. The package, developed by the authors in the freeware program Maxima, version 5.43.2, incorporates two commands which have a fairly intuitive syntax and allow the user indicating one or more elementary operations together so that they are applied to the rows (or columns) of a given matrix. Such features make it more effective and friendly than the default built-in commands in Maxima to perform such operations. In addition, our outputs are consistent with Maxima’s notation. Several illustrative examples, aimed to show the good performance of the package, are also given.
