How can I send data from one computer to multiple computers and receive data back from each one using UDP?

I read that UDP is good for real-time communications and broadcasting.

I am trying to implement a communication between several computers with matlab but I am sort of confused. As an example, I have to send the vector [a1 a2] to three computers andI each one performs a calculation. Computer A does a1+a2, computer B does a1*a2 and computer C does min(a1 a2) and send the results to the host. Finally, the Host receives the data from the three computers and performs a calculation: For example max(a1+a2,a1*a2,min(a1,a2))
