<p class="noindent">The use of these routines is described in this manual. Each chapter
72
provides detailed definitions of the functions, followed by example
73
programs and references to the articles on which the algorithms are
76
<p>Where possible the routines have been based on reliable public-domain
77
packages such as FFTPACK and QUADPACK, which the developers of GSL
78
have reimplemented in C with modern coding conventions.
