Suppose I have a numeric cell, i.e.

b= [1 2 3 4 5 6];
B= num2cell(b);

B= 
    [1]    [2]    [3]    [4]    [5]    [6]

How do I replicate the elements within cell
I want something like this:

C= 
   [2x2 double]  [2x2 double]  [2x2 double] [2x2 double] [2x2 double] [2x2 double]

where on expansion, the values within cell B is

C= 
     [1 1       [2 2
      1 1]       2 2] ........

If I use repmat, C= repmat(B,2,2), it replicates the whole cell and not the elements within cell

one of the solutions

     c=num2cell(1:4);
     cr=cellfun(@(x) repmat(x,2,2),c,'uni',false);
     cr{1}
%{
%    ans =
     1     1
     1     1
%}

num2cell can be avoided:
cr = arrayfun(@(x) repmat(x,2,2),b,'un',0);

Slightly faster:
cr2 = arrayfun(@(x) x.*ones(2),b,'un',0);

Much faster

b = 1:1e5;

tic
c = arrayfun(@(x) x.*ones(2),b,'un',0);
toc % 0.742264 seconds

tic
c = cell(size(b));
z = zeros(2);
for i=1:length(b)
    c{i} = z+b(i);
end
toc % 0.101876 seconds.
