Hi,
I have a 1x300 buffer full of timestamps called TimeBuffer. I want to find the dt (difference between each time stamp) and store this value in a separate array.
I've made a start:
i=2; dtarray = [];
while i<size(TimeBuffer,2)
dt(i)=TimeBuffer(i+1)-TimeBuffer(i);
dtarray = dt; <how to store??>
end
This doesn't give me an array of the difference between timestamps. Any help is appreciated.
Thanks

Your dt is itself is an array which grows in the loop as i increases, as i is the indices. And initialize dt before the loop to make it efficient.
i=1;
dt = zeros(1,length(Timebuffer)-1);
while i<length(TimeBuffer,2)
dt(i)=TimeBuffer(i+1)-TimeBuffer(i);
end
Or use diff to eliminate the loop.
