Implement three-axis inertial measurement unit (IMU)

**Library:**Vehicle Dynamics Blockset / Sensors

The Three-Axis Inertial Measurement Unit block implements an inertial measurement unit (IMU) containing a three-axis accelerometer and a three-axis gyroscope.

For a description of the equations and application of errors, see Three-axis Accelerometer and Three-axis Gyroscope.

Vibropendulous error, hysteresis affects, anisoelastic bias and anisoinertial bias are not accounted for in this block.

This block is not intended to model the internal dynamics of different forms of the instrument.
