Reshape and Repmat neatly

Hi,

Can anyone help me Reshape and Replicate columns efficiently in MATLAB, I can do it with reshape and repmat but is extremely messy and i'm sure theres a quicker and neater way.

e.g.

A = [ a b c 1 2 3 4 5 6 7 8 9; d e f 1 2 3 4 5 6 7 8 9 ]

to

B = [ a b c 1 2 3; a b c 4 5 6; a b c 7 8 9; d e f 1 2 3; d e f 4 5 6; d e f 7 8 9; ]

Thanks

Numbers and letters cannot be mixed in a numeric array.

@Simon: It would easier to create an answer, if you use a numeric matrix with unqiue values.

What is wrong with reshape and repmat? Reshape is extremely fast and some form of repmat is necessary since you want that much data at the end, i.e. you're not saving memory by avoiding rempat.

Instead of REPMAT a ONES as index can be used. But this happens inside REPMAT also.

Simon, if you are concerned about your solution being messy, why don't you post it? The community might be able to suggest a way to make it tidier.
