numpy.multiply
-
numpy.multiply(x1, x2, /, out=None, *, where=True, casting='same_kind', order='K', dtype=None, subok=True[, signature, extobj]) = <ufunc 'multiply'>
-
Multiply arguments element-wise.
Parameters: -
x1, x2 : array_like
-
Input arrays to be multiplied.
-
out : ndarray, None, or tuple of ndarray and None, optional
-
A location into which the result is stored. If provided, it must have a shape that the inputs broadcast to. If not provided or
None
, a freshly-allocated array is returned. A tuple (possible only as a keyword argument) must have length equal to the number of outputs. -
where : array_like, optional
-
Values of True indicate to calculate the ufunc at that position, values of False indicate to leave the value in the output alone.
- **kwargs
-
For other keyword-only arguments, see the ufunc docs.
Returns: -
y : ndarray
-
The product of
x1
andx2
, element-wise. Returns a scalar if bothx1
andx2
are scalars. This is a scalar if bothx1
andx2
are scalars.
Notes
Equivalent to
x1
*x2
in terms of array broadcasting.Examples
>>> np.multiply(2.0, 4.0) 8.0
>>> x1 = np.arange(9.0).reshape((3, 3)) >>> x2 = np.arange(3.0) >>> np.multiply(x1, x2) array([[ 0., 1., 4.], [ 0., 4., 10.], [ 0., 7., 16.]])
