[Numpy-discussion] np.ma.argmax not respecting the mask?

[Chao YUE]

Dear all,

I am using 1.7.1 version of numpy and np.ma.argmax is not repecting the
mask?
I expect for all data that are masked, it should also return a mask, but
this is not
the case.

In [96]: d3
Out[96]:
masked_array(data =
 [[-- -- -- -- 4]
 [5 -- 7 8 9]],
             mask =
 [[ True  True  True  True False]
 [False  True False False False]],
       fill_value = 6)


In [97]: np.ma.argmax(d3,axis=0)
Out[97]: array([1, 0, 1, 1, 1])

In [98]: np.__version__
Out[98]: '1.7.1'

Can I file a bug report on this?

thanks,

Chao
