How do I extend cell to a larger dimension.

I have a cell say A that I want to extend to the size of a larger cell, say B with special caracters, say 'n'. Similar to function padarray but with matrices. Say,

A = {'a','b';
     'c','d'};

B = cell(3,4);

C = fun(A,size(B),'n')

gives

C = {'a','b','n','n';
     'c','d','n','n';
     'n','n','n','n' }

If it's not too much to ask I would like the MATLAB way to do it, either using indexing or a modification of padarray. Thank you.

A = {'a','b';
   'c','d'};
C = repmat({'n'},3,4)
[n,m]=size(A)
C(1:n,1:m)=A

Thank you for your help. I was looking for an abstract way to do the last assignment.

[m,n] = size(A)
C(1:m,1:n) = A

The next step I found is:

[I1,I2] = ind2sub(size(C),1:numel(C));
C(I1 <= size(A,1) & I2 <= size(A,2)) = A;

And therefore would like something like,

C(ind2sub(size(C),1:numel(C)) <= size(A)) = A

But then I can't find the right parser for the indexing part...
