Repeating elements in an array,accessing elements

Question1: I have a resulting matrix from a gui as below: c =

Columns 1 through 6

    '000011000'    '001100111'    '000111011'    '001100100'    '011000000'    '001110001'

Columns 7 through 12

    '010010011'    '001000000'    '011001000'    '011000111'    '011010011'    '011001111'

Columns 13 through 16

    '010001000'    '000100000'    '001010111'    '011110001'

I am working in matlab R2013a version and I want each element of the above matrix to be repeated 3 times and the result be assigned to a new matrix D. (i.e if my matrix c was c=[111 101 100]; I want each element to repeat 3 times as D=[111 111 111 101 101 101 100 100 100])

I tried to use kron command and repelem command but both gives errors probably due to the version 2013a.Please help me with a code which will work in matlab R2013a The error is Undefined function 'times' for input arguments of type 'cell'.

Also I would like to know how to get c back once we have D.

Question 2:

When I have a matrix c as above when I type c(1,1) it gives the 1st element i.e 000011000. Is there a way to access each digit of the above element (like C(1,1)(1) , C(1,1)(2)...)?

Please help me with the above questions

Thanks a lot in advance.

You need to use cell arrays

c={'111' '101' '100'}
d=repmat(c,3,1)
d=d(:)'

if you want to access any digit

d{2}(3)
