[SciPy-user] arrays mean & NaN...

When I compute the mean of several arrays (the mean is an array),
and if one of several of these arrays has NaN in a given cell, the
mean of this cell is also NaN.

I would like to have the mean of the all non-NaN is this cell.

How could I do this ?

PS: To be more efficient, I don't mind if it is not the "right" mean, ie 
divided by the real
number of non-NaN, but the number of arrays.

But, just curious, I'm also interested by a solution for the right mean ;-)
