超声数值模拟

some matlab example for beginers

This submission enables MATLAB to access onboard Sensors on iPhone and iPad. With this submission, you can access a mobile device’s accelerometer, magnetometer, location, orientation and compass information directly from MATLAB running on your computer. You can access current and logged sensor data, and you can use MATLAB to visualize and analyze the mobile sensor data or make decisions based on the acquired data.
