Trying to count number of occurrences that exceed a threshold over a certain amount of time.

I am trying to count how many times the difference between two temperatures is less than 5 degrees. I want the code to only count the amount of times when the temperatures are within 5 degrees of eachother cosistently for 1 hour or more and ignore the times when they are within 5 degrees of each other for times shorter than 1 hour. I am doing data points that span 744 hours or one month.

if T is your temperature array.

dT = diff(T) ;
nnz(dT<5)
