Hello. I'm taking a class, Computational Physics, and I have to solve a few problems with PDEs. The topic was introduced and explained using a book oriented to Python; one of the examples solves the heat equation for a 1-D space and time by leapfrogging (time-stepping) the initial conditions forward in time. I don't have idea how to "translate" that code to Perl and I have searched for similar problems and their implementation in Perl but I found nothing. I'd like to know if exists a module for this kind of problems or website or book where I can find information about this.
