How to code signals? how would you code y[n] = x[n] + 0.4x[n-4096]?

%sound experianced: y[n] = x[n] + 0.4x[n-4096]
%use sound file handel.mat .... sampled at 8192 samples/sec
%compare with signal observed in the concert hall

I am to use y[n] and compare it to handel.mat. How would I code y[n]? I tried :

y= [0 zeros(1,1)]+ 0.4*[0 0 4096]; %y[n] = x[n] + 0.4x[n-4096]

but that was wrong

You probably need first to learn that MATLAB indexing uses parens, thus (), not square brackets, [].
