SciPy: A scientific computing package for Python
================================================
Documentation is available in the docstrings and
online at http://docs.scipy.org.
Contents
--------
SciPy imports all the functions from the NumPy namespace, and in
addition provides:
Subpackages
-----------
Using any of these subpackages requires an explicit import. For example,
``import scipy.cluster``.
::
cluster --- Vector Quantization / Kmeans
fftpack --- Discrete Fourier Transform algorithms
integrate --- Integration routines
interpolate --- Interpolation Tools
io --- Data input and output
lib --- Python wrappers to external libraries
lib.lapack --- Wrappers to LAPACK library
linalg --- Linear algebra routines
misc --- Various utilities that don't have
another home.
ndimage --- n-dimensional image package
odr --- Orthogonal Distance Regression
optimize --- Optimization Tools
signal --- Signal Processing Tools
sparse --- Sparse Matrices
sparse.linalg --- Sparse Linear Algebra
sparse.linalg.dsolve --- Linear Solvers
sparse.linalg.dsolve.umfpack --- :Interface to the UMFPACK library:
Conjugate Gradient Method (LOBPCG)
sparse.linalg.eigen.lobpcg --- Locally Optimal Block Preconditioned
Conjugate Gradient Method (LOBPCG) [*]
special --- Airy Functions [*]
lib.blas --- Wrappers to BLAS library [*]
