How do you append to a matrix within a for loop?

Hi, I am using a for loop to process data (this part works fine). What I need to do is take the matrix (A) and after each loop update A to create one matrix. For instance, in the image below A is produced on the first loop, during loop 2 A "grows" to include the data from loop 1 and the data from loop 2, and so on.

Loop 1 produces a matrix, on the next iteration I need to append to this matrix the results of that loop, and so on until all of the data is processed.
It should be noted that the number of rows on each loop is unknown. However, the number of columns is fixed to 7.
Any ideas would be greatly appreciated please.

% make an empty array
% the main command is end+1
N=[];
for i=0:10
x=i*i;
N(end+1)=[x]
end
