Making a vector with letters

hi everyone,

these codes work correctly with numbers but i change the numbers with letters it does not work.

if i write [1 2 3 4 5 6] in alphabet there is no problem. it works.

I need run this codes with letters

when I run it with latters the codes which name is "randsrs" give me a error.

error="Dimensions of matrices being concatenated are not consistent."

How can i fix this problem. What should i write instead of "randsrsc" codes?

i have to change {'a' 'b' 'c'} to [ a a b a c a b c a b]

please help me

alphabet    = ['a' 'b' 'c' 'd' 'e' 'f']
p = [.5 .125 .125 .125 .0625 .0625]
dict = huffmandict(alphabet,p)
sig = randsrc(1,10,[alphabet; p])
comp = huffmanenco(sig,dict)
dsig = huffmandeco(comp,dict)

@S.ANIL Ercetin: Note that in MATLAB [] are a concatenation operator, and are not a list operator as in some other languages (MATLAB does not have a list operator). This means that this:

alphabet    = ['a' 'b' 'c' 'd' 'e' 'f']

is actually equivalent to this:

alphabet    = 'abcdef'

and could be defined more generally using:

alphabet    = 'a':'f'

alphabet    = ['a' 'b' 'c' 'd' 'e' 'f'];
p = [.5 .125 .125 .125 .0625 .0625];
dict = huffmandict(num2cell(alphabet), p);
sig = char( randsrc(1,10,[double(alphabet); p]) );
comp = huffmanenco(sig,dict)
dsig = cell2mat(huffmandeco(comp,dict))

it exactly works, thanks for your help.
