Extract data at regular intervals

Asked by Dirk

Hi There,

I have 2 columns of data, time and concentration. The time data are at intervals of about 5 seconds and there is a corresponding concentration measurement at each time. There are about 20,000 time measurements and I want to reduce this to a more manageable amount. How can I obtain say every 10th time x concentration value?

Thanks

Accepted answer

Are you asking for just

X = ones(2e4,2);
Y = X(1:10:end,:);

Y is a two-column matrix containing every 10-th measurement (or measurements taken every 50 seconds).
