Hi. Ihave the same problem. Iwould like to know if you found a solution.
On the other hand I manage to send some data, except when I send data which consists of server sending data that,s whent it crashes.

Hi Harsh,
I understand that you are employing MATLAB's "tcpclient" function to initiate a connection with a server, and you wish to detect server disconnections and manage the error suitably.
There is no workaround currently for MATLAB R2017b. However, for MATLAB versions R2021b and later, a workaround can be implemented as described in the given thread:
