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) = [];
