Abstract—Abstract—Modeling of a dynamical system is an important research area to obtain mathematical models of real systems. There are several approaches to get mathematical models, one of them is utilizing the Lagrangian of holonomic systems. This paper introduces LagranTexPac, a package Matlab-based framework aimed at obtaining, and simulate the equations of motion of a mechanical system. LagranTexPac uses the Lagrangian function of a system to automatically generate the system equations of motion for numerically simulate and saves all phase portraits. Motion constraints can be included in Lagrangian, and a summary report can be generated. Utility of this software tool includes any engineer area, in which is used a Lagrangian function to obtain the equations of motion of a dynamic system, e.g., aerospace, biomedical, robotics and mechanical engineering. Three application examples are included to illustrate the usefulness of this software tool.
