I have a csv with 2 columns in, the first is the timestamp (2021-02-27 12:00:00), and the 2nd is heartrates. Ive calculated a moving average of the heartrate coulmn and wish to export the moving average values along with the timestamps as a new csv. Everything uve tried doesnt seem to work so any help would be much apprecieted.

data = readtable('2021-02-01.csv');
timeseriesmoving_average = movmean(data.HeartRate, minutes(20), 'SamplePoints', data.Timestamp);
data1 = [data.Timestamp, timeseriesmoving_average]
writematrix(data1,'data.csv');
Heres the code i used
