Simulation of transmembrane potentials and corresponding electrograms

This function simulates transmembrane potentials (for a 90 x 90 grid) and corresponding electrograms (for a 5 x 5 electrode grid) for a piece of human atrial tissue, based on the monodomain and Courtemanche [1] models and a model for electrograms [2]. This function was programmed to generate the simulation data as used in [3]. When using this function, please refer to the references below for completeness.
