Joshua - I think that your solution works well. An alternative is the following
Excell = mat2cell(cell2mat([Bill , Ted]),[1 1]);
where we just combine the two cell arrays as [Bill , Ted] and then convert it to a 2x10 matrix with cell2mat. We then convert back to a cell array as mat2cell(...,[1 1]) where we use the [1 1] to indicate the row dimensions of the new cell array.
