How to store in a separate array?

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.
