[Numpy-discussion] Problem with set_fill_value for masked structured array

[Thomas Robitaille]

Hi,

The following code doesn't seem to work:

import numpy.ma as ma

t = ma.array(zip([1,2,3],[4,5,6]),dtype=[('a',int),('b',int)])
print repr(t['a'])
t['a'].set_fill_value(10)
print repr(t['a'])

As the output is

masked_array(data = [1 2 3],
              mask = [False False False],
        fill_value = 999999)

masked_array(data = [1 2 3],
              mask = [False False False],
        fill_value = 999999)

(and no exception is raised)

Am I doing something wrong?

Thanks in advance for any help,

Thomas
