Hi there, I need some help of solving that issue: I have 5 different voltage values that change every single tick time - that mean every single moment. I need to sort them and after they been sorted I want to go to another matrix(like this one at the bottom) and to pull out(read) specific column from it. That mechanism change every single states/moment. How can I do this ?
The Matrix look like(and could be greater...):
0 0 0 1 1 1
0 1 1 0 0 1
1 0 1 0 1 0
1 1 0 1 0 0
Thanks, Henry

You should provide an example since your question is ambiguous. You say you have 5 values at each time, yet your example matrix has no 5-column or 5-row entries.
Look at sort() and sortrows() for sorting. For pulling out the column that you want, type
result = Matrix(:,col_I_want);
If you want to pull a row out, use
result = Matrix(row_I_want,:);

the following command read 2 and 3 column .
result = Matrix(:,2); % read second column result = Matrix(:,3); % read third column.
