COO.dot¶
- COO.dot(other)[source]¶
Performs the equivalent of
x.dot(y)
forCOO
.- Parameters
other (Union[COO, numpy.ndarray, scipy.sparse.spmatrix]) – The second operand of the dot product operation.
- Returns
The result of the dot product. If the result turns out to be dense, then a dense array is returned, otherwise, a sparse array.
- Return type
{COO, numpy.ndarray}
- Raises
ValueError – If all arguments don’t have zero fill-values.

Examples
>>> x = np.arange(4).reshape((2, 2)) >>> s = COO.from_numpy(x) >>> s.dot(s) array([[ 2, 3], [ 6, 11]], dtype=int64)
