MATLAB: Number of ACF lags must be a scalar

Question

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.

Hi,

try:

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

Best regards
