Hi again,
I think you should read a bit abot the ":"-operator, it is quite helpful ;)
a =
1 2 3 4
5 6 7 8
9 1 2 3
4 5 6 7
>> a=a(:,1:end-1)
a =
1 2 3
5 6 7
9 1 2
4 5 6
I also answered your last question. Did it help you? If so, please accept my answer, so other users know, that this solves the issue.

Another method:
a(:,end) = [];
