i have a matrix with two vectors
i want to classify this matrix depending on the second vector for exemple
i have this matrix:
  1. 1 2 3 4 5
  2. 23 3 15 1 32 4
MY MATRIX AFTER CLASSIFICATION WILL BE
  1. 4 2 6 3 1 5
  2. 1 3 4 15 23 32
| MY CODE|
clc;
n=5;
x= 100;
y=100;
net = [rand([1,n])*x;rand([1,n])*y]
%v=SORTROws

In just one line:
>> X = [1,2,3,4,5,6;23,3,15,1,32,4];
>> sortrows(X.',2).'
ans =
4 2 6 3 1 5
1 3 4 15 23 32

[~, idx] = sort(net(2,:));
sorted_net = net(:,idx);
