trying not to sort entire matrix just the columns that conforms the rule. the example is a =[8 6 7; 9 6 7; 10 7 8; 9 9 8; 10 9 8; 9 9 10; 10 9 10; 11 9 10]; I want to sort the rows according to 2 and 3 respectively, but if the value on the second row is greater than the value on the third row this columns should also be sorted by the first column descending. The answer should be: b = [8 6 7; 9 6 7; 10 7 8; 10 9 8; 9 9 8; 9 9 10; 10 9 10; 11 9 10]; any advice?

out = sort(a, 'descend');
for ascending order
sort(a, 'ascend');

a = [8 6 7; 9 6 7; 10 7 8; 9 9 8; 10 9 8; 9 9 10; 10 9 10; 11 9 10]; b = [8 6 7; 9 6 7; 10 7 8; 10 9 8; 9 9 8; 9 9 10; 10 9 10; 11 9 10]; b is the answer
