The special functions portion of Commons-Math contains several useful functions not
|
|
provided by <code>java.lang.Math</code>. These functions mostly serve as building blocks
|
|
for other portions of Commons-Math but, as others may find them useful as stand-alone
|
|
methods, these special functions were included as part of the Commons-Math public API.
