.. py:function:: data_split(x, y, ratio, maskname=None)

   Split data into training and validation sets.

   Randomly split the input data arrays into two sets based on the given ratio.

   :param x: The input features array.
   :type x: `numpy.ndarray`
   :param y: The target variables array.
   :type y: `numpy.ndarray`
   :param ratio: The ratio of data to use for the first split (e.g., 0.8 for 80% training).
   :type ratio: `float`
   :param maskname: If provided, save the split masks to a .npz file with this name.
   :type maskname: `str`, optional

   :returns: * **x1** (`numpy.ndarray`) -- The first split of input features.
             * **y1** (`numpy.ndarray`) -- The first split of target variables.
             * **x2** (`numpy.ndarray`) -- The second split of input features.
             * **y2** (`numpy.ndarray`) -- The second split of target variables.
