1) (10 points) Create a spreadsheet that allows the user to easily input the boundary temperatures for 4 edges and a center portion of a grid of at least 20 x 20. The non-specified interior cells should be calculated using Laplace's equation. The resulting data should be plotted using a surface plot. Adjust the rotation for a nice view. Be sure to label your axes and include the numbers on the boundary.
