% Compute r, v from range, range rate, az and el.
The algorithm is
r = [cos(az)*cos(el);sin(az)*cos(el);sin(el)];
v = pinv(r)'*range*rangeRate;
This is a fit to velocity. With 4 measurements v cannot be known
exactly. If one component is zero then the result will be exact.
Type AzElRangeRangDotToRV for a demo.

Form:
[r, v] = AzElRangeRangeDotToRV( az, el, range, rangeDot )
