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
-----------
::
odr --- Orthogonal Distance Regression [*]
misc --- Various utilities that don't have
another home.
cluster --- Vector Quantization / Kmeans [*]
fftpack --- Discrete Fourier Transform algorithms
[*]
io --- Data input and output [*]
sparse.linalg.eigen.lobpcg --- Locally Optimal Block Preconditioned
Conjugate Gradient Method (LOBPCG) [*]
special --- Airy Functions [*]
lib.blas --- Wrappers to BLAS library [*]
sparse.linalg.eigen --- Sparse Eigenvalue Solvers [*]
stats --- Statistical Functions [*]
lib --- Python wrappers to external libraries
[*]
lib.lapack --- Wrappers to LAPACK library [*]
maxentropy --- Routines for fitting maximum entropy
models [*]
integrate --- Integration routines [*]
ndimage --- n-dimensional image package [*]
linalg --- Linear algebra routines [*]
spatial --- Spatial data structures and algorithms
[*]
interpolate --- Interpolation Tools [*]
sparse.linalg --- Sparse Linear Algebra [*]
sparse.linalg.dsolve.umfpack --- :Interface to the UMFPACK library: [*]
sparse.linalg.dsolve --- Linear Solvers [*]
optimize --- Optimization Tools [*]
sparse.linalg.eigen.arpack --- Eigenvalue solver using iterative
methods. [*]
