hi there, I've separated the oxygen data set from a matrix of other data sets (measurements)
i used
rmmissing(Oxygen)
to remove the blanks and now need to convert the string to integers. Is the following correct?
Oxygen= Measurements(:,1);
%removing the extra <missing> strings
Oxygen=rmmissing(Oxygen);
%Data converted to integers
Oxygen = cellfun(@str2num, Oxygen,'UniformOutput',false)
also, how do i determine the frequency of measurements for Oxygen for measurements that are taken over a 24-hour time period?
Thanks
