The Markov matrix sequence of :
Mf={{0,1},{1,1}]--> Fibonacci
M0={{0,1,0},{0,0,1},{1,1,0}}--> Minmal cubic Pisot eigenvalues/ theta0 :
1-> {2,3}
M1={{0,1,0,0},{0,0,1,0},{0,0,0,1},{1,0,0,1}}-->Minmal quartic Pisot
eigenvalues/ theta1
1-> {1,4}
Produce tensor like sequences when used in a Markov
recursive manner.
(* Minimal Pisot 3by3 Markov sequence*)
digits=21
M={{0,1,0},{0,0,1},{1,1,0}}
i=IdentityMatrix[3]

A[n_]:=M.A[n-1];
A[0]:={{0,1,1},{1,1,2},{1,2,2}};
(* flattened sequence of 3by3matrices made with a Minimal Pisot recurrence*)
b=Flatten[Table[M.A[n],{n,0,digits}]]

MathReader 3.0, or any compatible application. The data for the notebook
starts with the line of stars above.
To get the notebook into a Mathematica-compatible application, do one of
the following:
* Save the data starting with the line of stars above into a file
with a name ending in .nb, then open the file inside the application;
* Copy the data starting with the line of stars above to the
clipboard, then use the Paste menu command inside the application.
Data for notebooks contains only printable 7-bit ASCII and can be
sent directly in email or through ftp in text mode. Newlines can be
CR, LF or CRLF (Unix, Macintosh or MS-DOS style).
NOTE: If you modify the data for this notebook not in a Mathematica-
compatible application, you must delete the line below containing the
word CacheID, otherwise Mathematica-compatible applications may try to
use invalid cache data.
