Hi, For a school project I need to send out a series of pulses on a high frequency. The problem is that I need code to be executed between every pulse.

For now I found this code:

%Initialise digital channel s (output) and m (input) and array a
For i = 1:n
    s.outputSingleScan(1)
    s.outputSingleScan(0)
    a(i)=m.inputSingleScan()
end

The problem with this method is that the signal only works whith a frequency of 38 Hz (the for loop is executed only 38 times a second). I need it to be at at least 1kHz.

Is there a way that I can speed up the code? Or is there a way that this can be done faster?

Thanks in advance.

Sometimes it is not just a matter of coding, but the machine you use to perform the operation. Anyway, check out the following links, they might help:

hi，have you solved this problem？The execution time of two lines of code has been more than 60 ms, and I am very painful.It is impossible to realize high frequency pulse.
