Jacobian of measurement function for constant velocity motion

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

= cvmeasjac(`state`

)`state`

specifies the current state of
the tracking filter.

also specifies the measurement coordinate system, `measurementjac`

= cvmeasjac(`state`

,`frame`

)`frame`

.

also specifies the sensor position, `measurementjac`

= cvmeasjac(`state`

,`sensorpos`

)`sensorpos`

.

also
specifies the sensor velocity, `measurementjac`

= cvmeasjac(`state`

.

specifies the measurement parameters,
`measurementjac`

= cvmeasjac(`state`
