Here's an example from the finance world. Let's say that you can't get a closed form solution for some option you are trying to price. One of the methods you may turn to is a finite difference method. You are going to have a series of equations to solve for the value at each grid point. A good understanding of linear algebra is essential if you want to code up your solution. You will be dealing with sparse matrices and tridiagonal matrices.
