Overview of Mathematics in IDL

This section documentsIDL's mathematics and statistics procedures and functions. These include Numerical Recipes™ algorithms published in Numerical Recipes in C: The Art of Scientific Computing (Second Edition). For a list of IDL mathematical routines, see the functional category of "Mathematics" (IDL Quick Reference). There you will find a brief introduction to the routines. Detailed information is available in the IDL Reference Guide. This section also includes introductory discussions of the following topics and an overview of the way IDL handles the particular problems involved:

References are provided at the end of each section for a more detailed description and understanding of the topic.
