Timeseries.png

Hello Everyone,

I am not really good at matlab and I am dealing with a time series data. The times series format is dd/mm/yyyy, I have attached a picture of the format.

My time series ranges from 1949 to 2017, my problem is if I want to delete a specific year in this time series, lets say 1949 along with data that comes with it...How do remove it from my time series?

I tried a bunch of time series commands such as delsample...but it didn't work. I don't know how to get about this.

If more information is needed please let me know,

Thank you.

在 MATLAB Online 中打开

Assuming your data is in variable ts, and using the example of wanting to delete multiple years:

mask = ~ismember(year(ts.Time), [1949, 1950]);
new_ts = getsamples(ts, mask);

在 MATLAB Online 中打开

Year = year(ts.Time/24 + datenum(ts.TimeInfo.StartDate));
mask = ~ismember(Year, 1949);
new_ts = getsamples(ts, mask);
