Aliases for functions which may be accelerated by Scipy.
|
||
|
|
|
||
|
|
Scipy_ can be built to use accelerated or otherwise improved libraries
|
||
|
|
for FFTs, linear algebra, and special functions. This module allows
|
||
|
|
developers to transparently support these accelerated functions when
|
||
|
|
scipy is available but still support users who have only installed
|
||
|
|
NumPy.
