Since all the vectors in your cell array have all different numbers of columns but just one row, the only matrix you can put them all together is a row vector, which you'd achieve with

rowvector = [yourcellarray{:}]

There is no way to concatenate the vectors in a 3d matrix unless you first add or remove elements in these vectors so they're all the same size.
