Argmin with several minimums

I would like to find a function returning, given an array Data of doubles, an array containing all the indices of Data's minimums. Does it exist?
Edit: How to do in the particular case the minimum is 1?

I think an example would be clearer.
I search a function Fun that returns:
Fun([1 2 3]) --> 1 Fun([2 3 6 8 4 9 2]) --> [1 7] Fun([1 0 1 0 1 0 1 0]) --> [2 4 6 8]
Is it clearer? Does this exist?

It doesn't feel very satisfactory, but this will do the trick
I = find(A == min(A))

Yes, that will work for vector input. It will not work for array inputs, which have not really been ruled out yet (giving an example with vectors is not the same thing as saying that non-vectors will not be used.)
