Systems with memory-Function for

Hello
Excuse me, how can I enter the following function in matlab?
y[n]=x[n]+x[n-1]
I have the vector [1 0.5 0.75 0.5 1] that corresponds to each value of n evaluated.
n=0:5
My code is
clc
clear all
vec=[1 0.5 0.75 0.5 1 0];
for i=1:6
n2= i-1;
ynum= vec(i)+ vec(n2);
y= ynum./2;
hold on
stem (i,y)
end
and the error that matlab tells me is
Array indices must be positive integers or logical values.
Error in Memoriafunejemplo (line 8)
ynum= vec(i)+ vec(n2);
Thank you very much for your comments!

@Mechelle Zarahi Fuentes Perez, MATLAB indexs are 1 based so vec(n2) is invalid since n2 is zero the first time through your loop. You must decide how y(1) is to be defined.

vec=[1 0.5 0.75 0.5 1 0]
vm = movmean(vec, 2)
plot([vec; vm].')
