Loop that pads at the top of the sinogram with 100 copies of its top row and at the bottom with 100 copies of its bottom row

How would I create a Loop from this script that pads at the top of the sinogram with 100 copies of its top row and at the bottom with 100 copies of its bottom row.

Proj_sino1024_ROIpadded=[proj_sino1024_ROI(1,:); proj_sino1024_ROI];
Proj_sino1024_ROIpadded=[proj_sino1024_ROI; proj_sino1024_ROI(size(proj_sino1024_ROI,1),:)];

Don't use a loop. If you have IPT, just do this:

outpict=padarray(inpict,100,'replicate','both');

If you don't have IPT, you can do

outpict=cat(1,repmat(inpict(1,:),[100 1]),inpict,repmat(inpict(end,:),[100 1]));

Great, thank you. The IPT script worked perfectly!
