negative(x, out=None, **kwargs)

Numerical negative, element-wise.

  • x (ndarray or scalar) – Input array.

  • 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.


y – Returned array or scalar: y = -x. This is a scalar if x is a scalar.
