generation of t-codes in matlab

Hi, I need t-codes to be generated in matlab. An example is shown below on how to construct t-codes example: suppose S = {0, 1} is an alphabet. We then remove one of the elements of the set and use it as a prefix to extend the initial set so that we get more [login to view URL] us take an example, let us use the first element 0 as the prefix. The new code set therefore is S(0)= {1, 00, 01}. For the next level, If we use 1 as the prefix, we get the set S(0, 1)= {00, 01, 11, 100, 101}; and if we use 00 as the prefix, we would get the set S(0, 00) = {1, 01, 001, 0000, 0001}; and if we use 01 prefix, then the resultant set S(0, 01) = {1, 00, 011, 0100, 0101}. The total number of elements in the T-code set at T-augmentation level n is 2n+1. The Input would be the number of augmentaion levels that is 'n' ... and the output would be th resultant codeset. If you can give some sort of demo that would be great!!!
