Performs the equivalent of for COO.

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.
