Hi, 
I have an array which is 465x323 elements. It is the 'x' co-ordinates for some data I am plotting in 3D, so I need to extend into 465x323x4, i.e just repeat the same array over.
At the moment I do:

X=cat(3,X,X,X,X)

This could get very lengthy if the 3rd dimension was 10 or more long...Is there a better way?
