I am looking to generate an 8x8 tridiagonal matrix with random integers, how do I do this?

n = 10
full(gallery('tridiag',n,rand,rand,rand))

You're nearly there. Rather than passing a scalar, pass 3 random vectors. If you want integers, use randi to generate them:

n = 8;  %size of matrix
range = [1 50]; %range of integers
full(gallery('tridiag', n, randi(range, 1, n-1), randi(range, 1, n), randi(range, 1, n-1)))

Thanks guillaume seems to be working

n = 10;

x=round(10*rand()); % random integer Value between [0 10]

y=round(10*rand()); % random integer Value between [0 10]

z=round(10*rand()); % random integer Value between [0 10]

full(gallery('tridiag',n,x,y,z))
