Why is Autocorrelation not working correctly??

hi,

please help!

I am trying to run autocorr function. it's located in C:\Program Files\MATLAB\R2014a\toolbox\econ\econ

however, the function returns:

"Undefined function 'autocorr' for input arguments of type 'double'."

please help!

Type in

which autocorr

at the command line and when you type

license('test','econometrics_toolbox')

you should see it return a value of 0 or 1. If it returns 0, then you don’t have the toolbox installed, if not then I suggest trying xcorr. By using the same array twice, the cross correlation should be equal to an autocorrelation.

crossCorrelation = xcorr(signal, signal); % This is the 1D case

crossCorrelation = xcorr2(signal, signal); % This is the 2D case

I typed in

>> which autocorr C:\Program Files\MATLAB\R2014a\toolbox\econ\econ\autocorr.m % Has no license available

>> license('test', 'econometrics_toolbox')

ans = 0 But I tried typing in VER and shows the econometrics toolbox is installed!
