Combine 2D matrices to form 3D one in Matlab

Question

I have 3 20x2 double arrays A, B and C. I want to combine them in one 3d array D so that D(:,:,1)

Answer 1

Using cat to concatenate along the third dimension might be the elegant way -

D = cat(3,A,B,C)

Here, the first input argument 3 specifies the dimension along which the concatenation is to be performed.
