How to create cell followed by uniform distribution?

I need to create a cell of size n*m which will follow uniform distribution. I can easily create a cell of size 3*2 by the following data set:

a=3; b=8; n=3; m=2;

A={{round((b-a).*rand(1,3) + a)} {round((b-a).*rand(1,3) + a)}; {round((b-a).*rand(1,3) + a)} {round((b-a).*rand(1,3) + a)}; {round((b-a).*rand(1,3) + a)} {round((b-a).*rand(1,3) + a)}};

it resuts

A=

3×2 cell array

{1×1 cell} {1×1 cell}

{1×1 cell} {1×1 cell}

{1×1 cell} {1×1 cell}

where A{1,1}=[8 4 6], A{1,2}=[4 6 3].......etc. How can I generate such cell with less effort for larger size because creating 10*20 size cell in this way is almost impossible?

z = arrayfun(@(x){round((b-a).*rand(1,3) + a)},1:3*2,'un',0);
A = reshape(z, 3, [])
