Cobine two cell arrays with Nested Cellfun

Hi all,

I have two cell arrays : A = {'13','15','17,'18'}; B = {'16','18','20','22','24',25','26','27,'28'};

I want to comine them and create a new cell array (of size 1x36) such that each element in the cell array is of the form '13x16','13x18',....'13x28','15x16',....'15x28',...'18x16',....'18x28'

I thought of using a nested cellfun for this like shown below : Combi = cellfun(@(x) cellfun(@(y) [x, 'x', y],B,'Uniform',false), A,'Unifrom',false);

However I get an error saying 'Input #3 expected to be a cell array, was char instead'

Any ideas what could be going on ?

[b,a] = ndgrid(B,A);
out = strcat(a,{'x'},b);

Tried this but does not seem to work. First of all the ndgrid function returns an error 'Undefined function 'full' for input arguments of type 'cell'...
