Hi
I have an array which is 1 X 55 (Called TempStorage) which is updated each iteration of the loop I want to store this information form TempStorage into my 2 D array 3X55 (Called DecodeData) so the first iteration of the loop I want to store TempStorage into DecodeData(row One) and on the second loop store TempStorage into DecodeData(row Two) and on the third loop store TempStorage into DecodeData(row three) how do I declare TempStorage and DecodeData, and how do I send the data from TempStorage to DecodeData(x)
I dont have much experience with Matlab any help would be greatly appreciated
David

N = 3;
DecodeData = nan(N,55);
for k = 1:N
TempStorage = ... whatever defines your 1x55 vector
DecodeData(k,:) = TempStorage;
end
Very basic MATLAB concepts, like how to use loops and how to allocate data using indexing, are introduced here:

Hi Stephen
Thank you for your answer it worked great, perhaps you can help me with the second part of my question ?
The 55 bits relate to 4 data bits then a parity bit do you no how I can seperate them out in an array to be able to check the parity
Thank You
David

"The 55 bits relate to 4 data bits then a parity bit do you no how I can seperate them out in an array to be able to check the parity"
What class are the data: numeric, char, or something else?
It would be highly unusual (and misleading) to refer to numeric values as "bits", so I presume that you must have some kind of binary data, presumably as a character vector. If the fifth bit (i.e. fifth element of the character vector) represent parity, then you can refer to it using indexing, e.g.
TempStorage(5)
Without concrete examples of your data I have to rely on guessing, which is usually not very accurate.
