i am trying to calculate the average peak values in a systolic pressure waveform during a specific time interval. for example, every 5 seconds, i want to average out all the peak values in that interval and after calculating the average, i want to delete the array of peak values. however, what i am finding is that the array is always 0 if i use the delete array in my vi. therefore, the average is always NaN, because the array is empty and there is a divide by 0 error.... what should i do? i have been stuck on it for a long time now, thankyou very much
