- Return a string representation of the data in an array.
-
- The data in the array is returned as a single string. This function is

- returns information on the kind of array and its data type.
-
- Parameters
- ----------
- a : ndarray
- Input array.
- max_line_width : int, optional
- Inserts newlines if text is longer than `max_line_width`. The
- default is, indirectly, 75.
- precision : int, optional
- Floating point precision. Default is the current printing precision

- suppress_small : bool, optional

- Set a Python function to be used when pretty printing arrays.

- Parameters
- ----------
- f : function or None
- Function to be used to pretty print arrays. The function should expect
- a single array argument and return a string of the representation of
- the array. If None, the function is reset to the default NumPy function
- to print arrays.
- repr : bool, optional
- If True (default), the function for pretty printing (``__repr__``)
- is set, if False the function that returns the default string
- representation (``__str__``) is set.

-
- `repr` affects either pretty printing or normal string representation.
- Note that ``__repr__`` is still affected by setting ``__str__``
