[Numpy-discussion] byte swap in place

[Christopher Hanley]

Hi,

Is there a way to byte swap a ndarray in place?  The "byteswap" method I 
have found on an ndarray object currently returns a new array.

Example:

In [16]: a = n.array([1,2,3,4,5])
In [17]: a
Out[17]: array([1, 2, 3, 4, 5])
In [18]: b = a.byteswap()
In [19]: b
Out[19]: array([16777216, 33554432, 50331648, 67108864, 83886080])
In [20]: b[0] = 0
In [21]: b
Out[21]: array([       0, 33554432, 50331648, 67108864, 83886080])
In [22]: a.dtype
Out[22]: dtype('<i4')
In [23]: b.dtype
Out[23]: dtype('<i4')

Thank you for your time and help,
Chris
