why when i make conv between an averaging filter and a noisy circuit it doesn't get filtered?

n=0:499
x=sin(2*pi*n/50)
y=x+0.1*randn(size(n))
h=[11111]/5
z=conv(h,y)

if anyone find error

Answer 1

You need commas between the ones in h:

n=0:499
x=sin(2*pi*n/50)
y=x+0.1*randn(size(n))
h=[1,1,1,1,1]/5
z=conv(h,y)

n=0:499;
x=sin(2*pi*n/50);
y=x+0.1*randn(size(n));
h=[1,1,1,1,1]/5;
z=conv(y,h,'same');

it doesn't make change
