creating a diagonal matrix in matlab

[charlieryan]

hi

I'd like to create a matrix that looks something like;

a c 0 0 0 0
b a c 0 0 0
0 b a c 0 0
0 0 b a c 0
0 0 0 b a c
0 0 0 0 b a

Where b, a, and c are contants. I'l like to be able to set the matrix size as well [the matrix should be square].
Any ideas
thanks!

Charlie

Hi,

one of the many solutions :

n=6;
toeplitz([a b zeros(1,n-2)],[a c zeros(1,n-2)])
