Return filtered values from a matrix

I have expressed my problem with the following image. I would like to implement exactly what I am saying on matlab but I am confused about how to do it.

hi

what have you done so far ?

I am trying to express it as a code but I am getting confused... I would like to have something like that, [max,min,rightmaxcell,leftmax,cell]=Algorithm(Function). I am trying to create a function which will return these values max,min,rightmaxcell,leftmax,cell. But I can't.

data = [321 -0.2; 937 -0.18; 23 -0.16; 472 -0.15; 964 -0.14; 375 -0.13; 902 -0.12; 462 -0.11; 842 0; 735 1; 328 2; 341 2.5; 421 3]

data = 13×2

321.0000 -0.2000 937.0000 -0.1800 23.0000 -0.1600 472.0000 -0.1500 964.0000 -0.1400 375.0000 -0.1300 902.0000 -0.1200 462.0000 -0.1100 842.0000 0 735.0000 1.0000

range_limits = [-0.3 -0.1];

range_limits = sort(range_limits);
in_range_rows = find(data(:,2) >= range_limits(1) & data(:,2) <= range_limits(2));
[max_val,idx] = max(data(in_range_rows,1));
max_row = in_range_rows(idx);

disp(max_row)

     5

disp(data(max_row,:))

  964.0000   -0.1400
