bsparse.zeros

zeros(bshape, dtype=<class 'float'>, sizes=None, symmetry=None, format='bcoo')

Create an empty sparse matrix of specified bshape and dtype.

Parameters:

bshapetuple[int, int]

The bshape of the matrix.

dtypenp.dtype, optional

The data type of the matrix elements, by default float.

symmetrystr, optional

The symmetry of the matrix, by default None.

formatstr, optional

The sparse format of the matrix, by default “coo”.

Returns:

BSparse

An empty sparse matrix of specified bshape and dtype.

Examples

>>> bdia = zeros((3,3), format="bdia")
>>> bdia
BDIA(bshape=(3, 3), bnnz=0 | shape=(3, 3), nnz=0)
>>> bdia[0, 0]
COO(shape=(1, 1), nnz=0, dtype=float64)
