Extracting Corresponding values from an array

if I have 2 dimensional matrix , How can I create a function which takes , for example, a value from the first colmn in the matrix and ouputs the corresponding value in the the second colmn (and same row)?

Thank you so much!

Example usage, function defined below.

matrix = [1 2; 3 4; 5 6; 1 8]

matrix = 4×2

1 2 3 4 5 6 1 8

get_2nd_column_val(matrix,3)

ans = 4

get_2nd_column_val(matrix,1)

ans = 2×1

2 8

% function definition
function out = get_2nd_column_val(data,in)
out = data(data(:,1) == in, 2);
end
