   Numerical and Statistical functions

   Most of these functions take an "axis" argument, which indicates whether to
   operate over the flattened array (None), rows (0), or columns (1).





.. function:: argmax(array, \*, axis=None)

   Return the index of the maximum element of the 1D array


.. function:: argmin(array, \*, axis=None)

   Return the index of the minimum element of the 1D array


.. function:: argsort(array, \*, axis=None)

   Returns an array which gives indices into the input array from least to greatest.


.. function:: diff(array, \*, axis=1)

   Return the numerical derivative of successive elements of the array, as
   an array.  axis=None is not supported.


.. function:: flip(array, \*, axis=None)

   Returns a new array that reverses the order of the elements along the
   given axis, or along all axes if axis is None.


.. function:: max(array, \*, axis=None)

   Return the maximum element of the 1D array


.. function:: mean(array, \*, axis=None)

   Return the mean element of the 1D array, as a number if axis is None, otherwise as an array.


.. function:: min(array, \*, axis=None)

   Return the minimum element of the 1D array


.. function:: roll(array, distance, \*, axis=None)

   Shift the content of a vector by the positions given as the second
   argument. If the ``axis`` keyword is supplied, the shift is applied to
   the given axis.  The array is modified in place.


.. function:: sort(array, \*, axis=0)

   Sort the array along the given axis, or along all axes if axis is None.
   The array is modified in place.


.. function:: std(array, \*, axis=None)

   Return the standard deviation of the array, as a number if axis is None, otherwise as an array.


.. function:: sum(array, \*, axis=None)

   Return the sum of the array, as a number if axis is None, otherwise as an array.
