How are you everyone! I need your help to solve this problem :
If I have an image which contains columns with all elements equal to zero , how can delete the columns?
For example , if I have the image
A= [ 1 0 2 3 4 ;0 0 5 4 3 ;5 0 7 6 5;3 0 4 3 0]
How can I delete the second column ? The result I want is
AA=[1 2 3 4 ;0 5 4 3 ;5 7 6 5 ;3 4 3 0]
Any answer will be appreciated Thank you.

A= [ 1 0 2 3 4 ;0 0 5 4 3 ;5 0 7 6 5;3 0 4 3 0]
AA=A(:,any(A))

Or
A(:, ~any(A)) = [];
To actually delete the columns.

A= [ 1 0 2 3 4 ;0 0 5 4 3 ;5 0 7 6 5;3 0 4 3 0]
A =
1 0 2 3 4
0 0 5 4 3
5 0 7 6 5
3 0 4 3 0
A(:,2)=[];
A =
1 2 3 4
0 5 4 3
5 7 6 5
3 4 3 0
