I have a matrix like this: Data = [2,1,4,6,2;9,4,6,1,2;5,3,2,8,3;7,2,1,9,3;7,1,8,2,4]
2 1 4 6 2
9 4 6 1 2
5 3 2 8 3
7 2 1 9 3
7 1 8 2 4
then i want to exclude the column 3 and 5 from my new matrix. So it will be like this:
2 1 6
9 4 1
5 3 8
7 2 9
7 1 2
what to do? thanks before :')

simple way would be:
Data(:,3) = []; Data(:,5) = [];

then you would remove one column first and then change the value accordingly, only a simple solution. Although I agree that Data(:, [3, 5]) = []; is better.

so, solution from andrei below is same with you. and it works :)

Data = [2,1,4,6,2;9,4,6,1,2;5,3,2,8,3;7,2,1,9,3;7,1,8,2,4]
out = Data(:,[1 2 5])
