join cell arrays together

let us assume that I have this cell array

x =

5×1 cell array

{'the_output'}

{'the_output'}

{'the_output'}

{'the_output'}

{'the_output'}

and I have another cell array

y=

5×1 cell array

{[1]}

{[2]}

{[3]}

{[4]}

{[5]}

I want matlab to combine x and y to form, let us say, another cell array called z and it's value

z =

5×1 cell array

{'the_output1'}

{'the_output2'}

{'the_output3'}

{'the_output4'}

{'the_output5'}

I want this to be done without using loops and conditions statements

Answer 1

[madhan ravi]

cellstr(string(x)+string(y))

Answer 2

[Fangjun Jiang]

x=repmat({'the_output'},5,1);
y=mat2cell((1:5)',ones(5,1),1);
z=cellfun(@(a,b) [a,num2str(b)],x,y,'UniformOutput',false)
