numpy.subtract(x1, x2[, out]) =
Subtract arguments, element-wise.
Parameters: |
x1, x2 : array_like The arrays to be subtracted from each other. |
---|---|
Returns: |
y : ndarray The difference of |
Equivalent to x1 - x2
in terms of array broadcasting.
>>> np.subtract(1.0, 4.0) -3.0
>>> x1 = np.arange(9.0).reshape((3, 3)) >>> x2 = np.arange(3.0) >>> np.subtract(x1, x2) array([[ 0., 0., 0.], [ 3., 3., 3.], [ 6., 6., 6.]])
