How to solve linear equations using numerical methods?
In Linear Algebra, we learned that solving systems of linear equationscan be implemented by using row reduction as an algorithm. However, when these meth-ods are not successful, we use the concept of numerical methods. Numerical methods are used to approximate solutions of equations when exactsolutions can not be determined via algebraic methods.
