How to change cell arrays to 3D arrays in order to speed up calculations?

Hello, For example I have two cell arrays x {10}(20x5) non integer values and k {10}(5x1) integer values 1:5, and use one cell array as index to other array.
x1=cellfun(@(x,y) x(5,y),x,k, 'UniformOutput',false);
and result is x1 {10}(1x5), unfortunately cell fun is slow with gpuArray when working with bigger arrays, what would be the way to use 3D arrays and maybe arrayfun for this?

An example would be if
x(:,:,1)
1 8 10 2 5
3 5 7 9 11
4 5 2 3 7
12 10 4 6 2
9 7 10 1 3
.....
and k(:,:,1)
3
4
1
5
3
then x1(:,:1) would be
10 1 9 3 10
