BobH, the actual problem is that OP wants to do it with lots of matrices, so manually concatenating array will not be practical.

If the data is stored properly, i.e., in cell array instead of using separate variables, the following one-liner will work
a{1}=[1,2,3; 4,5,6; 7,8,9];
a{2}=[10,11,12; 13,14,15; 16,17,18];
a{3}=[19,20,21; 22,23,24; 25,26,27];
C = cell2mat(cellfun(@(x) x(:)', a, 'UniformOutput', 0)')';
