Yes, it is possible.
You can send data between systems by using a serial port, or by using a parallel port, or by converting the data to audio signals and converting the audio back to data, or by connecting the two systems with a network cable and using UDP or TCP, or by installing WIFI on the systems and transferring the data wirelessly; or by other similar methods.
There are too many different possibilities for anyone to show sample code for each of the possibilities. You should narrow down your choices.
How far away will the systems be from each other? Is a physical cable between them practical? Does the environment have a lot of electromagnetic noise? Will there be a microwave oven operating nearby? What rate will the data transfer need to occur at? What is the maximum acceptable delay between the time that one system starts sending data and the time the data is available to MATLAB on the second system?
