What to use instead of horzcat for N-D Arrays?

Hello.

I have a 3D array (let's say 3 x 4 x 100, call it AA) and want to add zeros to the end of the long dimension (let's say to get it to 3 x 4 x 200, adding on BB that is also 3 x 4 x 100 with zeros). horzcat() isn't happy, and [AA BB] won't do it.

Suggestions? Thanks!

AA(end,end,200) = 0;

The horzcat function concatenates horizontally, in dimension 2.

The vertcat function concatenates vertically, in dimension 1.

The cat function lets you concatenate in whatever dimension you specify. As shown in the example on the cat documentation page, you want to concatenate in dimension 3.

Thank you Steven -- that's also great.
