SciPy: A scientific computing package for Python
================================================
Documentation is available in the docstrings and
online at https://docs.scipy.org.
Subpackages
-----------
Using any of these subpackages requires an explicit import. For example,
``import scipy.cluster``.

constants --- Physical and mathematical constants and units
datasets --- Dataset methods
differentiate --- Finite difference differentiation tools
fft --- Discrete Fourier transforms
fftpack --- Legacy discrete Fourier transforms
integrate --- Integration routines
interpolate --- Interpolation Tools
io --- Data input and output
linalg --- Linear algebra routines
ndimage --- N-D image package
odr --- Orthogonal Distance Regression
optimize --- Optimization Tools
signal --- Signal Processing Tools
sparse --- Sparse Matrices
spatial --- Spatial data structures and algorithms
special --- Special functions
stats --- Statistical Functions
Public API in the main SciPy namespace
--------------------------------------
::
__version__ --- SciPy version string
LowLevelCallable --- Low-level callback function
show_config --- Show scipy build configuration
test --- Run scipy unittests
