Set the sampling rates. In a typical system, the accelerometer and gyroscope in the IMU run at relatively high sample rates. The complexity of processing data from those sensors in the fusion algorithm is relatively low. Conversely, the GPS runs at a relatively low sample rate and the complexity associated with processing it is high. In this fusion algorithm the GPS samples are processed at a low rate, and the accelerometer and gyroscope samples are processed together at the same high rate.

Robot Operating System (ROS) is a communication interface that enables different parts of a robot system to discover each other, and send and receive data between them. MATLAB® supports ROS with a library of functions that enables you to exchange data with ROS-enabled physical robots or r

This function determines the message type of entity and apples the appropriate transformation method to it. If the object cannot handle a particular message type, then MATLAB® displays an error message. If you want to use only the most current transformation, call transform instead. If you want to store a transformation message for later use, call getTransform, and then call apply.

ROS Toolbox provides an interface connecting MATLAB® and Simulink® with the Robot Operating System (ROS and ROS 2), enabling you to create a network of ROS nodes. The toolbox includes MATLAB functions and Simulink blocks to import, analyze, and play back ROS data recorded in rosbag files. You can also connect to a live ROS network to access ROS messages. The toolbox lets you verify ROS nodes via desktop simulation and by connecting to external robot simulators such as Gazebo. ROS Toolbox supports C++ code generation (with Simulink Coder™), enabling you to automatically generate ROS nodes from a Simulink model and deploy to simulated or physical hardware. Support for Simulink external mode lets you view messages and change parameters while your model is running on hardware.

对单端输入差分放大电路发射极耦合传输的分析方法进行了深入研究，利用电路分析的方法将单端输入信号等效变换成差模输入信号、共模输入信号的叠加，指出等效变换时并不需要发射极电阻Re很大的条件，Re的取值大小只反映对共模输入信号的抑制程度。与输入信号用数学方法等效变换进行了对比，得出两种输入信号的等效变换方法具有等效性的结论。并介绍了单端输入差分放大电路的教学处理方法。
