An-Introduction-to-Programming-and-Numerical-Meth
This text provides an introduction to the numerical methods that are typically
encountered (and used) in science and engineering undergraduate courses. The
material is developed in tandem with MATLAB which allows rapid prototyping
and testing of the methods. The package MATLAB (matrix laboratory) pro-
vides an environment in which students can learn to programme and explore
the structure of the numerical methods. The methods included here are of a
basic nature and only rely on material which should have been explored prior
to the fi rst year undergraduate stage.
