replicating the elements of a cell matrix

Dear all,

here is a cell matrix

 k={
12 'kol'
23  'Sew'         
45  'awe'        
44 'wow'         
}

I would like to replicate each element twice so as to have

 k={

 12 'kol'

 12 'kol'
23  'Sew' 
23  'Sew'        
45  'awe'  
45  'awe'      
44 'wow'
44 'wow'         
}

I was thinking something like

      cr=cellfun(@(x) repmat(x,2,1),k,'uni',false);

but I do not know if I am correct. Is there any better code?

Would there any difference if I had

 k={
'12' 'kol'
'23'  'Sew'         
'45'  'awe'        
'44' 'wow'         
}

thanks

Here's one way:

nk = size(k,1);
idx = [1:nk;1:nk];
k(idx(:),:)

if I wanted to replicate each element of the above matrix 1000 times instead of 2 how could I modify your code?

Use

idx = repmat(1:nk,[1000 1]);

in place of the second line.

repelem(k,2,1)
