2. By using the general framework introduced in class, complete the Matlab package of linear and quadratic finite element methods for the 10 second order elliptic equation with Dirichlet/Neumann/Robin boundary conditions and maximum/L2/H1 error measurements. For numerically solving Examples 1-4 in the lecture slides of Chapter 1, write your main code to call your package with the following requirements: (a) I can directly run the main code in the Matlab command window by simply using the name of the main code without inputting any parameters by me. (b) After I run the main code, the Matlab command window will show me the errors in the infinity norm, L2 norm, and H1 semi-norm for the mesh size h=1/4, 1/8, 1/16, 1/32, 1/64, 1/128, 1/256. 2.
