- cupy.ptp(a, axis=None, out=None, keepdims=False)[source]#
Returns the range of values (maximum - minimum) along an axis.
The name of the function comes from the acronym for ‘peak to peak’.
When at least one element is NaN, the corresponding ptp value will be NaN.
a (cupy.ndarray) – Array over which to take the range.
axis (int) – Axis along which to take the minimum. The flattened array is used by default.
out (cupy.ndarray) – Output array.
keepdims (bool) – If
True, the axis is retained as an axis of size one.
