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.

在 MATLAB Online 中打开

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

  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
