Hello Fei,

If you have already used the custom messages with publishers and subscribers within MATLAB, then you should be able to use with within Simulink without any further changes. If the message shows in "rosmsg list", it should be available in Simulink.

If you have only used the custom messages in a ROS installation outside of MATLAB, you need to generate the message definitions within MATLAB as well. See this overview and this example for instructions on how to bring custom messages into MATLAB. You will need this support package.
