How to combine multiple GF arrays into 1 big GF array

Hi,

I am creating a Hamming(7,4) code and am holding the contents in a 1x7 gf array. The goal is to take a message such as "hello" (in 8 bits per character) turn it to binary and add the Hamming(7,4) code to it then combine it all back as one. The Hamming code can only do 4 bits at a time so it is returning a 1x7 GF array. For "hello" I obtain 10 1x7 GF arrays. Is there a way to combine these arrays into one big one GF array? Or make it a 2d array? So have an array hold each 1x7 cell array? Is there a way to append the 1x7 to the big array? I am new to MATLAB so I am not sure of all of the processes .

Thank you
