[Numpy-discussion] ANN: numpy.i - added managed deallocation to ARGOUTVIEW_ARRAY1 (ARGOUTVIEWM_ARRAY1)

[Egor Zindy]

Hello list,

I've moved my wiki to the scipy cookbook:
http://www.scipy.org/Cookbook/SWIG_Memory_Deallocation

For the time being, the listed example files are still stored on the google
code SVN, but these could easily be moved if necessary.

I've also just finished adding an ARGOUTVIEWM_ARRAY2 example. The example
shows how to return a two-dimensional array from C which also benefits from
the automatic memory deallocation.

A naive "crop" function is wrapped using SWIG/numpy.i and returns a slice of
the input array. When used as

array_out = crop.crop(array_in, d1_0,d1_1, d2_0,d2_1)

it is equivalent to the native numpy slicing

array_out = array_in[d1_0:d1_1, d2_0:d2_1]


Hope this helps!

Regards,
Egor
