How to control external machinery by matlab?

How can I control an external machine, for instance to advance to the next sample after finishing a measurement?

You can use Simulink Real-Time to achieve this. Please refer to the following product page for more information: https://in.mathworks.com/products/simulink-real-time.html

Thank you for your answer, but this is not what I am looking for. I don't use Simulink, and I just want to output 1 bit or maybe 1 byte using Matlab only.
