MATLAB: How to index all columns but one in a matrix

Question

Hi!

I want to do index/use all columns in a matrix but a single one, so for example:

A=[1 2 3 4; 1 2 3 4; 1 2 3 4] and I 'd like to get at B=[1 2 4; 1 2 4; 1 2 4].

A long way to that would be: B=[A(:,1:2),A(:,4)], but is there anything faster/built in?

Best Peter

Answer 1

B = A;
B(:,3) = [];
