How can I count number of dates over 100 degree F?

1 view (last 30 days)
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!!

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

dates = readtable('your_dates_file');
% assume that your dates fie has only one column
temps = readtable('your_temperature_file');
% 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);
