COMPUTING METHODS

The student should have some knowledge of the C programming language and of the Unix

environment. In particular he should be acquainted with concepts like: Flow diagrams, conditions

and If statements, for and while loops, arrays, pointers, functions, file input/output.

Moreover, he should be able to use simple numerical methods for integration, like the Euler and the

Monte Carlo method, and for the solution of simple differential equations.

As an introduction to C and a review of the basic concepts, one can use any book on C

Programming or one of the many free web resources available online, e.g.:

https://www.learn-c.org

https://www.coursera.org/specializations/c-programming

Numerical methods are presented in, e.g., Numerical Recipes in C: The Art of Scientific

Computing, by B. P. Flannery, S. Teukolsky, W. H. Press, and W. T. Vetterling
