MATLAB: How to return value of column not the index using find function

Question

I have a simple matrix

 A=   
    1  3
    4  2
    2  1
    3  3
    5  2

I'd like to search for all values in the first column whose second column is 3

When i use

    find(A(:,2)==3)

I returns the index not the value of the first column?

Is there any matlab function that can do this?

That in advance

Answer 1

 out= A(A(:,2)==3,1)

Also, with your code you found the indices

idx=find(A(:,2)==3)

The the result is

R=A(idx,1)
