there are more than 1 element satisfy the command in one column, but I only need to count it one time

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));

Try this:

maxTemp = max(data(:,4:end),[],2);
Above41 = nnz(maxTemp > 41)

producing:

Above41 =
     3
