Description

From the listing uploaded by “appupdater”.

Solve systems of linear equations using the methods of elimination of Gauss, Gauss - Jordan and the method of Stile also known as "Algorithm of Bariess", with this useful application you will obtain the result and the necessary steps to reach the solution. You can also calculate the determinant of a matrix using the Gauss method and the Sarrus method, although the latter is only applicable to arrays of order 3x3. This app is designed for university students, as well as for professional engineers who perform matrix calculations in their work.
