Thread Subject: writing in a loop

I want to recode the following codes in a loop. I am very new so I am always getting error for my recodings. Can you help me ? How to rewrite this in a loop?

 myImg=[s(:,:,1),del,s(:,:,2),del,s(:,:,3),del,s(:,:,4),del,s(:,:,5),del,s(:,:,6),del,s(:,:,7),del,s(:,:,8);
        del.',0,del.',0,del.',0,del.',0,del.',0,del.',0,del.',0,del.';

I assume the dimensions of "s" to be (otherwise can't concatenate):
s = ones(32,1,64);

del=zeros(32,1);
Output = NaN(size(s,1), 64*2-1);
IDX1 = 2:2:64*2-1;
IDX2 = 1:2:64*2;
Output(:,IDX1) = repmat(del,1,length(IDX1));
Output(:,IDX2) = s(:,:,1:64);

thanks Oleg,
this gives dimension mismatch error for
                   Output(:,IDX1) = repmat(del,1,length(IDX1));

I have defined that s=zeros(32,32);
and from my image I have done this assignment:
                        s(:,:,k)=p(X1:X2, Y1:Y2);
then I have written the above codes.

Are there any solution ? I think, it is possible to write the above codes in a loop but how ?
