2D analogue of the WHERE function? [message #66359]

Dear all,

Haven't found a thread mentioning this problem, which I can't
understand as it seems like something someone would have mentioned
before.

Anyway, to get to the point: Is there an equivalent of the WHERE
function that will scan a multidimensional array, and return a set of
indices for the elements that match the criteria?

I'm trying to pick out certain pixels of a FITS image, and the only
way round the problem I can think of is to loop the WHERE function
over one of the dimensions. Does a more elegant solution exist?

Many thanks,

Stefan
