Hi,
I'd like to know the first index (and eventually the value) of the minimum element larger than zero in a vector.
Exemple : a=[14,9,4,-1,-6,-11,9,4,-1] , I look for "3" (and eventually the value = 4)
Any suggestion is kindly appreciated
thanks

a=[14,9,4,-1,-6,-11,9,4,-1] ;
[val,idx] = min(abs(a))
val = 1
idx = 4

Thanks KSSV, but nope: that's index "4" and value "-1". I look for index "3" and value "4"
