SPHERE2UVW is the jSphere module of jLab.

 SPHERE2UVW Converts a 3D spherical vector to a 3D Cartesian vector.
    [U,V,W]=XYZ2SPHERE(LAT,LON,V1,V2,V3) converts a vector in spherical
    coordinates with components V1, V2, and V3 located at point 
    (LAT, LON) into a Cartesian 3-vector with components U, V, and W.
    LAT and LON are in degrees.
    The vector in the spherical coordinate system has radial component
    V1, longitudinal component V2, and latitudinal component V3.   
    The Cartesian vector [U,V,W] is in a reference frame with the
    X-axis at zero degrees longitude and the Z-axis at the North Pole.  
    All input arguments should be arrays of the same size.
    SPHERE2UVW is inverted by UVW2SPHERE.
    See JSPHERE for related functions.
    Usage: [x,y,z]=sphere2uvw(lat,lon,v1,v2,v3);
