spmatrix

class scipy.sparse.spmatrix

This class provides a base class for all sparse matrix classes.

It cannot be instantiated. Most of the work is provided by subclasses.

Attributes:

shape

Shape of the matrix

Methods

__mul__(other)
asfptype()	Upcast matrix to a floating point format (if necessary)
getH()	Return the Hermitian transpose of this matrix.
get_shape()	Get the shape of the matrix
getcol(j)	Returns a copy of column j of the matrix, as an (m x 1) sparse matrix (column vector).
getformat()	Matrix storage format
getmaxprint()	Maximum number of elements to display when printed.
getnnz([axis])	Number of stored values, including explicit zeros.
getrow(i)	Returns a copy of row i of the matrix, as a (1 x n) sparse matrix (row vector).
set_shape(shape)	Set the shape of the matrix in-place
todense([order, out])	Return a dense representation of this sparse matrix.
