hello, experts,
I am new to Matlab community and a beginer to use it
I have a dataset (refer as attachment)
data = textread('January-2018-Adelaide.csv', '', 'headerlines', 1, 'delimiter', ',');
and would like to count how many days satisfy the cammand
which is the temerature exceed 41.0
however, in some days, there are more than one temerature exceed 41.0
and if i use
n_days_above = numel(find(temperatures>41));
it will be count more than one time (it shows: n_days_above =7, but the correct answer is 3 )
how can I solve this problem?
thank you in advanced!
data = textread('January-2018-Adelaide.csv', '', 'headerlines', 1, 'delimiter', ',');
temperatures = data(:, 4:end);
n_days_above = numel(find(temperatures>41));

Above41 = nnz(maxTemp > 41)
producing:
Above41 =
