LinearSolver is an app that designed to solve systems of linear equations with n variables. You enter equations in the field, then choose solving method and press a button «Solve». Then program solves your linear system. There are two methods for solving: Gaussian elimination and Cramer's rule. For more intelligibility enable the «detailed solution».
Von Neumann entropy
