How to smooth time series?

Hello guys,

I'm having this error with tsmovavg, Error using fints/tsmovavg (line 80), I'm trying to smooth the price data corresponding to 30 days, this is the code I have written

price = fints(Date, data); price = price'; plot(price); lag = 30; exponential = tsmovavg(price, 'e', lag, 2); plot(price);

Invalid number of inputs. Please see 'help fints/tsmovavg'

I appreciate any help, thanks guys :)

isn't the problem that you have transposed price and stored it in price and then used it in tsmovavg? price = price'; ???? store it in some plot_price = price'; and then plot(plot_price);
