Consider the nonlinear BVP
-u" + e-u=1,
u(0) = u(1) = 1.
Use finite difference techniques to reduce this approximately) to a system of nonlinear algebraic equations, and solve this system using several of the methods discussed in this chapter. Test the program on the sequence of grids h-1 = 4,8,.... 1024 (and further, if practical on your system). Compare the cost of convergence for each method in terms of the number of iterations and in terms of the number of operations.

In this exercise you will work with LU factorization of an matrix A. Theory: Any matrix A can be reduced to an echelon form by using only row replacement and row interchanging operations. Row interchanging is almost always necessary for a computer realization because it reduces the round off errors in calculations - this strategy in computer calculation is called partial pivoting, which refers to selecting for a pivot the largest by absolute value entry in a column. The MATLAB...
