sparray

class scipy.sparse.sparray(arg1, *, maxprint=None)

This class provides a base class for all sparse array and matrix classes. It cannot be instantiated. Most of the work is provided by subclasses.

Attributes:

T

Transpose.

format

Format string for matrix.

imag

mT

Matrix transpose.

ndim

nnz

Number of stored values, including explicit zeros.

real

shape

size

Number of stored values.

Methods
