Measurement function for constant turn-rate motion

returns the measurement for a constant turn-rate Kalman filter motion model in
rectangular coordinates. The `measurement`

= ctmeas(`state`

)`state`

argument specifies the
current state of the filter.

also specifies the measurement coordinate system, `measurement`

= ctmeas(`state`

,`frame`

)`frame`

.

also specifies the sensor position, `measurement`

= ctmeas(`state`

,`frame`

,`sensorpos`

)`sensorpos`

.

also
specifies the sensor velocity, `measurement`

= ctmeas(`state`

,`frame`

,`sensorpos`

,`sensorvel`

)`sensorvel`

.

specifies the measurement parameters,
`measurement`

= ctmeas(`state`

,`measurementParameters`

)`measurementParameters`

.
