What should i add more to create decent autocorr func.

t= rand(100) ; %% ‘I have created 100 point random sampled f(t)’

mean(t); %% ‘calculated mean’

var(t); %% ‘calculated variance’

Now how can i create autocorrelation function for f(t)

Hi,

To create autocorrelation function using given time series ‘t’, ‘t’ should 1 x n array (or vector). Modify the existing code as given below to create autocorrelation function.

t= rand(1,100) ; %% 1 x 100 array with 100 random values   
m = mean(t); %% ‘calculated mean’  
v = var(t);  %% ‘calculated variance’ 
autocorr(t); 

In the code above ‘t’ is vector instead of a matrix.

Hope this helps.

Thank you. Now i see
