How to downsample a matrix in columns ? MATLAB [closed]

I am studying wavelets in image processing. I would like to learn how to downsample a matrix in columns using MATLAB. I have used the downsample(x,n) command to downsample the given matrix in rows. But how to do the same in columns?

x =

1     2     3
4     5     6
7     8     9
10    11    12

y = downsample(x,2)

y =

1     2     3
7     8     9

But I would like to get the following result.

y=
1       3
4       6
7       9
10      12

Maybe Off-Topic here, but anyway !

Try it

y = downsample(x',2)'
• Thanks a lot .. It works.. It's simple. Don't know how I missed it. Thanks again. – Premnath D Nov 8 '13 at 17:30

Do not use the downsample function.

I used simple method in MATLAB:

x= [1 2 3;
4 5 6;
7 8 9;
10 11 12];

x1=x(:,1:2:end)

Have a good time. ^^
