How to make a transition table in MATLAB that includes all the elements defined?

Attaching a code written in MATLAB , how to make a transition table out of it??

i=0:2;

j=0:2;

k=0:2;

Np = 2; %last state number for each entry, states are numbered from 0 to Np

K=2;

A=fullfact([3 3 3 3 3 3])-1;

B = char(A+'0');

%fill in the appropriate values for these probabilities. rand() is used to have some value

Index = @(B) 1+B; %helper to allow us to use state numbers instead of indices

case1_src_i = 0:Np-1;

lam_p;

syms gam_p ; %gamma subscript p

syms gam_f ; %gamma subscript f

syms bet_w ; %beta subscript w

syms gam_r ; %gamma subscript r

TT = zeros( Index (ones(1, 12) )); %transition table

I am confused about this line of code, How can I generate a transition table that intakes all the 729 values of B as an input.

{ T2 = reshape(TT, B.^6, B.^6); %2D transition table Error using reshape Size arguments must be integer scalars.

T2 = reshape(TT, Index.^6, Index.^6); %2D transition table Undefined function 'power' for input arguments of type 'function_handle'.

Kindly help. Please suggest what to write in order to generate a transition table?

What is wrong with bold code lines? Why am I not getting the transition table?
