information about the number of times temperature changes from negative to positive

2 views (last 30 days)
Hello
I have a time series with daily temperatures. The time series is starting with negative temperature. After some days the temperature is shifting from negative to positive and after some days back to negative. How can I get information about the number of times the temperature has changed from negative to positive.

*Consider the temperatures as a vector a
count=0;
for i=1:length(a)-1
if a(i)<0 && a(i+1)>0
count=count+1;
end
end
disp(count);
