A sparse matrix package based on Eigen.

Project description

SpPy is a sparse matrix library based on the C++ library Eigen with a similar interface to NumPy. Here is a code snippet:

::

>>> import numpy
>>> from sppy import csarray
>>> #Create a new column major dynamic array of float type
>>> B = csarray((5, 5), storagetype="col")
>>> B[3, 3] = -0.2
>>> B[0, 4] = -1.23
>>> B[numpy.array([0, 1]), numpy.array([0,1])] = 27
>>> print(B)
csarray dtype:float64 shape:(5, 5) non-zeros:4 storage:col
(0, 0) 27.0
(1, 1) 27.0
(3, 3) -0.2
(0, 4) -1.23
>>> print(B.sum())
52.57
