Small program that allows you to find critical points, gradient, and Hessian of a 2 or 3 variable function. Very useful for mathematical analysis students. Completely written in User RPL.
Program for solving eigenvalues and vectors problems with the "potencias" method. It includes a program that allows you to find the eigenvalues and vector of the inverse matrix. Very handy for students in numeric methods class. All written in RPL.
A couple of programs for solving differential equations by the Runge Kutta method. It allows you to solve problems by using Euler's method and also Runge Kutta's second order methods. Very useful for calculus students in the Universidad Nacional de Cuyo and for any numeric method student. Written in User RPL for all 49/50 series models.
