AzElRangeRangeDotToRV:

Path: AerospaceUtils/Coord

% 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.

 Since version 9.
