Instruction: Implement the finite difference method in one-dimensional and include the graphical output of the solution and the error. Use comments to describe the steps you are doing.

Model problem: -u''(x) + a u(x) = f(x)

Dirichlet conditions:

u(x_0) = u_0

u(x_n) = u_n

Note:

Define, the coo matrix then convert it csr.
