Imagine a thin metal plate surrounded by heat sources along each edge, with the edges held at different tem- peratures. After a short time, the temperature at each location on the plate will settle into a steady state. This can be modeled by dividing the plate into a discrete grid of cells and simulating the change in temperature of each cell over time: 100 100100 100 100 90 T(2,1)T(2,2)T(2,3)95 90 (3,1)T(3,2)T3,3)95 80 80 80 80 10 At each time step, the temperature in each interior cell (i.j) will be the average of four of its surrounding neighbors
