How can I see the full matrix when I use spdiags() ?

Hey there,

I am currently using the function spdiags and the outcome is the following:

An:

(1,1) 4

(2,1) -1

(1,2) -1

(2,2) 4

(3,2) -1

(2,3) -1

(3,3) 4

(4,3) -1

(3,4) -1

(4,4) 4

with this particular input : An = spdiags([- ones(n ,1) , 4* ones(n ,1) , - ones(n ,1)] , [ -1 , 0 , 1] , n , n)

Is there perhaps a way to see the full matrix instead of just this?

Thanks in advance!
