Jacobian of measurement function for constant-acceleration motion

returns the measurement Jacobian, for constant-acceleration Kalman filter motion
model in rectangular coordinates. The `measurementjac`

= cameasjac(`state`

)`state`

argument specifies
the current state of the filter.

also specifies the measurement coordinate system, `measurementjac`

= cameasjac(`state`

,`frame`

)`frame`

.

also specifies the sensor position, `measurementjac`

= cameasjac(`state`

,`frame`

,`sensorpos`

)`sensorpos`

.

also
specifies the sensor velocity, `measurementjac`

= cameasjac(`state`

,`frame`

,`sensorpos`

,`sensorvel`

)`sensorvel`

.

specifies the measurement parameters,
`measurementjac`

= cameasjac(`state`

,`measurementParameters`

)`measurementParameters`

.
