+
+ Return a contiguous flattened array.
+ A 1-D array, containing the elements of the input, is returned. A copy is
+ made only if needed.
+
+ Parameters
+ ----------
+ x : ndarray
+ Input array. The elements in `x` are read in row-major, C-style order
and
+ packed as a 1-D array.
+ out : ndarray or None, optional
+ A location into which the result is stored. If not provided or `None`,
+ a freshly-allocated array is returned.
+
+ Returns
+ -------
+ y : ndarray
+ y is an array of the same subtype as `x`, with shape ``(x.size,)``.
+ Note that matrices are special cased for backward compatibility, if `x`
+ is a matrix, then y is a 1-D ndarray.
+
+ Notes
+ -----
+ This function differs from the original numpy.arange in the following
aspects:
+ - Only support row-major, C-style order.
