MatLab help! newbie question!

[martinisonline]

how can i represent on matlab this equation:

h[n]=d[n]+2*d[n-2]-2*d[n-3]

d[n] is the unit impulse sequence

u can do it as shown below

% declare d
% declare value of n
% for example

d = [ 4, 3, 6, 3, 2, 3, 8, 2, 7, 4]

for n=4:10
h = d + 2*d(n-2) - 2*d(n-3);
end
