[Numpy-discussion] fill_value in masked arrays

[Keith Goodman]

The doc strings for MaskedArray and ma.argsort do not seem consistent.

The doc string for MaskedArray says "The fill_value is not used for
computation within this module." But the doc string for ma.argsort
says "Treating masked values as if they have the value fill_value,
return sort indices for sorting along given axis."

I'm trying to argsort matrices that have missing values.
