Hello! I have a dataset with daily maximum temperatures and daily minimum temperatures from the 1930s to 2020. I have one data file with the dates and another one with the corresponding temperatures. I want to create a loop (or anything that works) to know how many days are above 100F and how many days are below 32F. Any suggestions?
Thank you!!

Can you share your dataset form so as to write code for you

Yes! I extracted the daily maximum temperatures and daily minimum temperatures from a bigger dataset.
Thank you!

% assume that your dates fie has only one column
% assume that your temperature file has two columns, one is minimum T(°F), the
% other is maximum T (°F)
minT = temps{:,1};
maxT = temps{:,2};
p = minT<32; % or <=
q = maxT>100; % or >=
dates_below_32 = dates(p,:)
dates_above_100 = dates(q,:);
num_of_days_below_32 = sum(p);
num_of_days_above_100 = sum(q);
