MATLAB: How to select matrix column from minimum row value

Question

I am currently doing a multi-part task, but the final step involves sorting a matrix I generated to find the lowest value in the row and selecting the whole column:

eg:

distance_to_point = [2, 3, 4, 5; 6.8, 2.9, 6.1, 6.7]

I need to pick the column that has the lowest value in the second row (the distance value), and still identify the point from which the distance is measured, so that I end up with;

new_point = [3; 2.9]

How would I do this?

Answer 1

distance_to_point = [2, 3, 4, 5; 6.8, 2.9, 6.1, 6.7]
[~,idx] = min(distance_to_point(2,:));
new_point = distance_to_point(:,idx);
