Number of ACF lags must be a scalar

Hi there,

I have one basic question just it has been bothering me for a day. This is the code:

Table=readtable('rGDP.csv');
gdpacf = autocorr(Table.GDP,'NumLags',10);

run it and I keep getting the error msg:

Error using autocorr (line 99)
Number of ACF lags must be a scalar.

Error in test (line 3)
gdpacf = autocorr(Table.GDP,'NumLags',10);

If instead I run gdpacf = autocorr(Table.GDP), everything's fine. So what's wrong with 'NumLags',10 ?

Thanks a lot.

Which release do you use?

[Xin Shen]

R2017a, if that's what you are asking?

Hi,

try:

Table=readtable('rGDP.csv');
gdpacf = autocorr(Table.GDP,10);

Best regards

If my answer was useful, make sure to accept it.

To avoid those kind of problems use the documentation site for the Matlab Release you use.

Worked. Just realize that version difference can be this significant. Will pay attention going forward. Tks!
