Supposing that there is an array X=[9,2,3,5,1,6,8,4,7], how can I find
the first and second minimums (in this array are elements 1 and 2) in
this vector?

I use this to find the first minimum (element 1):

index = where(X eq min(X))
minimum_first=X[index]

But, how can i find the elements 2 ?
thanks
