Merge multiple 3D arrays matlab

Question

I have a 3 sets of CT data each in it's own 700x700x512 array and I want to merge them into just one single array.

I had a look at the cat() function but didn't really understand how you set the dim variable- ie say for two simple 3x3x3 arrays, A & B, can I use AB_merge = cat(dim, A, B);

Thanks for any help!

Answer 1

The dim variable sets along which dimension you want to concatenate the images.

So if you want them 'on top of each other' that is along the 3rd dimensions:

AB_merge=cat(3, A, B);

If it is side by side along the x-axis:

AB_merge=cat(1, A, B);

etc.
