Geodetic Vector to ECEF

How do I transform a vector given in geodetic coordinates (e.g. Wind Northwards/Eastwards in m/s, depending on latitude/longitude/height) into the ECEF (x,y,z) system?

I am aware of the function "[X,Y,z] = geodetic2ecef(spheroid,lat,lon,h)", however this only transforms a single coordinate rather than a vector in m/s.
