Select from 2D Array by 2 criteria - Matlab

I have a 15 * 2 array where the first column represents the area and the second column represents the corresponding circularity to the 15 objects. I need to select the row with maximum area while applying the following condition for the circularity to be > 0.9 and <= 1.2

Example:

• Area Circularity
• ----- -----------
• 22041 1,1703
• 23458 2,8425
• 155 1,4165
• 37 2,1089
• 215 1,5692
• 41 1,0549
• 659 1,7144
• 64 1,0508
• 3 0,3092
• 584 1,2543
• 26 1,1132
• 396 2,9046
• 1 0
• 3 0,8488
• 4 0,4638
• Expected Result:
• 22041 1,1703

Answer 1

Try this:

y = your 2D matrix
x = y(:,2) > 0.9 & y(:,2) <= 1.2;
z = y(x,:);
[~,k] = max(z);
result = z(k,:);

filteredarray = yourarray(yourarray(:, 2) > 0.9 & yourarray(:, 2) <= 1.2, :);  %filter unwanted rows
[~, maxrow] = max(filteredarray(:, 1));   %find location of max in what's left over
result = filteredarray(maxrow, :)    %get the row at location
