Exercise 1.4.26 The steady state temperature, u, of a plate solves Laplace's equation, Au= 0. One way
to approximate the solution is to divide the plate into a square mesh and require the temperature at each
node to equal the average of the temperature at the four adjacent nodes. In the following picture, the
numbers represent the observed temperature at the indicated nodes. Find the temperature at the interior
nodes, indicated by x, y, z, and w. One of the equations is z = (10+0+w+x).
