I have to simulate in Matlab the variation of temperature in a metal plate/block, heated at just one end. One suggestion I received is that I have to use partial differential equations and the energy balance law but I don't know how to start. I study computer science, so physics is a bit off to me. I've read about conduction and Fourier's law, but it just confused me even more. I just need a start on how is this variation on temperature determined in physics.
