I am having 322759 rows. It means 322 seconds. How can I average the mili seconds data and convert in to seconds. I just want 322 rows(322 seconds). Accordingly the next column should also average up according to the time. Attaching a sample

Data=(1:25)';
Ten=10;
NofData=floor(length(Data)/Ten)*Ten;
temp=reshape(Data(1:NofData),Ten,[])
temp = 10×2
1 11 2 12 3 13 4 14 5 15 6 16 7 17 8 18 9 19 10 20
av=mean(temp)
av = 1×2
5.5000 15.5000

You may want to use imresize:
Table=readmatrix('ms_to_sec.csv');
Table=imresize(Table,[322,2]);
Table(:,1)=1:322;
