With a cell array, {} operates on the content of the cells, () operates on the cell array itself.
So, to crop a cell array:
newcellarray = yourcellarray(1:end-1);
Note that
yourcellarray{indices}
edit: so a convoluted way of also cropping the cell array (as long as it is a row cell vector) would be:
newcellarray = {yourcellarray{1:end-1}};
which would unpack all the elements but the last into a comma-separated list and repack it into a new cell array. A bit convoluted!
