Hi... my name is fahrul. I try to filtering for smoothing my data in format file txt. In this file, there are 3 coloumns. first is date, second is time and the last coloumn is value of tide. I used two coloumns data, date and velue only to plot in matlab. Anybody can help me to make syntax filtering by using moving average??

If data is the array with your values and t is date/time:
plot(t, smooth(data));
