an implementation problem in matlab using gaussian function

[rupkotha]

hei,

can anyone help me with implementation of the function in MATLAB please:

y=1/n*summation of x(R); where n=1,2,3....N
use N=100
or 1000
and x(R) is a gaussian random variable with zero mean and variance=1
plot x and y VS n in the same plot.

thanks.
( i dunno why this summantion sign is not working.. !:?)
