 This block receives ROS messages of type ''std_msgs::Float64''. Each time the block is run by its time domain, the message content is written to the output of the block.
 <code cpp>
-  RosSubscriberDouble pubDouble("myNode/myTopic"); // create subscriber block
+  RosSubscriberDouble subDouble("myNode/myTopic"); // create subscriber block
