Getting minimum value from an array

I want to get min of A= [0, 20, 15]. Actualy I want to find the minimum excluding the zero. So in the example my answer would be 15 not zero. Finaly I want to get the index of the minimum value. What I have done so far looks like:

    for i=1:size(A)
       if A(i)~=0
           [index,c]=find(min(A));
       end
    end

but it is not giving me the results I want.

Answer 1

[Thomas]

try

c=min(A(A~=0))
idx=find(A==c)

Answer 2

[Sean de Wolski]

[val index] = min(A(~~A))

If you wanted the index involving zeros, find it after

index = find(A==val,1,'first')

thanx Sean it gives the correct Value but the index is not quit correct. It gives me 2, i think it should give 3.

[Sean de Wolski]

look at the second part. Where we calculate the index after using find.
