Finding the Right Function
The IMSL C Math Library is organized into chapters; each chapter contains functions with similar computational or analytical capabilities. To locate the right function for a given problem, you may use either the table of contents located in each chapter introduction, or in Alphabetical Summary of Functions at the end of this manual.
Often the quickest way to use the IMSL C Math Library is to find an example similar to your problem and then mimic the example. Each function in the document has at least one example demonstrating its application.
