MATLAB Script for Sending Data to Multiple Devices, Study Guides, Projects, Research of Network Programming

Babasaheb Bhimrao Ambedkar UniversityNetwork Programming

This matlab script outlines a function that sends data to multiple devices based on the number of nodes and their respective device names. For each node, the script reads an image and creates a struct with the 'simu' field containing the image data and the 'stat' field containing the status message. If the master device is selected, an error message is displayed instead. The function supports up to eight nodes.
