Matlab Timer: how to use right data with drops?

Goodmorning everyone,

my application idea is pretty simple: I want to send through TCP/IP a row of a matrix at a fixed rate.

I wanted to used Timer function to unlock Matlab execution from the data stream.

The period is lower than my execution time. This is not a problem for my application, but I would like to send a specific row related to the specific timer execution, and I don't know how to do it properly.

As an example: I have a N x 6 matrix, and I have to send one row at each execution of the timer function. Let's say that the Period is 1s and function execution time is 1.3s.

T = 0 -> 1st execution of TimerFnc -> send row n° 1

T = 1s -> drop (TimerFnc is running)

T = 2s -> 2nd execution of TimerFnc -> send row n° 3

T = 3s -> drop (TimerFnc is running)

T = 4s -> 3rd execution of TimerFnc -> send row n° 5

As a result, the receiver should lose some data (which is not a problem), but at least it will receive the most "up to date" information, and will not back up.

Is there a way to do this?
