scipy.sparse.csc_matrix.astype¶
-
csc_matrix.
astype
(self, dtype, casting='unsafe', copy=True)[source]¶ Cast the matrix elements to a specified type.
- Parameters
- dtypestring or numpy dtype
Typecode or data-type to which to cast the data.
- casting{‘no’, ‘equiv’, ‘safe’, ‘same_kind’, ‘unsafe’}, optional
Controls what kind of data casting may occur. Defaults to ‘unsafe’ for backwards compatibility. ‘no’ means the data types should not be cast at all. ‘equiv’ means only byte-order changes are allowed. ‘safe’ means only casts which can preserve values are allowed. ‘same_kind’ means only safe casts or casts within a kind, like float64 to float32, are allowed. ‘unsafe’ means any data conversions may be done.
- copybool, optional
If
copy
is False, the result might share some memory with this matrix. Ifcopy
is True, it is guaranteed that the result and this matrix do not share any memory.
