Toolbox for angle, coordinate and date conversions and transformations. Version 2.97.

[x,y,z]=sph2xyz(az,va,d)
function [x,y,z]=sph2xyz(az,va,d)
% SPH2XYZ  Converts spherical coordinates to Cartesian
%   coordinates in a left-handed (local geodetic) system.
%   Vetorized. See also XYZ2SPH.
% Version: 7 Jul 96
% Useage:  [x,y,z]=sph2xyz(az,va,d)
% Input:  az - vector of azimuths (radians)
%         va - vector of vertical angles (radians)
%         d  - vector of distances (linear units)
% Output: x \
%         y  > cartesian coordinates (linear units)
%         z /
