First minimum larger than zero

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"

[KSSV]

 a=[14,9,4,-1,-6,-11,9,4,-1] ;
 a(a<=0) = NaN ;
 [val,idx] = min(a)

val = 4

idx = 3

Ok thanks, that's working!

Okok, needed to figure it out. Then you can edit the first answer with the comment you did after ;-)
