I have a 4 column matrix. I want to find the value corresponding to the minimum value of column 2. How to find it?

I have a matrix, A

A=[1 2.4 3.4 5;2 -0.2 3 4;3 8.1 3.2 4;4 0.5 5 2]

I want to find the value in column 1 corresponding to the minimum value of column 2. For example, for this case, the minimum value of column 2 would be -0.2 and the value corresponding to that in column 1 is 2. How to get to this value? I tried this:

min(A(:,2),1)

But I am not getting the desired result. Can anyone help me with it?

A=[1 2.4 3.4 5;2 -0.2 3 4;3 8.1 3.2 4;4 0.5 5 2];
[minvalue,index]=min(A(:,2));
A(index,1)

ans =
