Diagonalization of a transfer matrix

Hello everyone:

I would like to know how to diagonalize a transfer matrix. Does Matlab have a code or toolbox for it???

Thanks ^U^

 Hello Abel.
 Code is "diag". Threedioganal matrix elements:
"diag(x,1)= upper-diagonal matrix element"
"diag(x,0)= diagonal matrix element"
"diag(x,-1)=lower-diagonal matrix element"
             | 0  1  x  x  x |
             |-1  0  1  x  x |
             | x -1  0  1  x |
             | x  x -1  0  1 |
             | x  x  x -1  0 |

diag() does not do diagonization: it only extracts elements from the matrix (or, in the other form, inserts them in to a matrix.) This is completely different from (say) LU decomposition.
