mmaxPositiveStreak

mmaxPositiveStreak(X, window)

Please see mFunctions for the parameters and windowing logic.

Obtain the maximum value of the sum of consecutive positive numbers in X within a sliding window of given size (based on the number of elements).

x = 1 -1 1 -2 10 3 3 9 0 6 5
w = 5
mmaxPositiveStreak(x, w)
// output
[,,,,10,13,16,25,25,15,12]

x = 5 NULL 3 2 1 5 10 9 NULL 9 10 -1 NULL
w = 5
mmaxPositiveStreak(x, w)
// output
[,,,,6,11,21,27,25,24,19,19,19]

// use the signum function to count the maximum number of consecutive positive numbers
mmaxPositiveStreak(signum(x), w)
// output
[,,,,3,4,5,5,4,3,2,2,2]
