function R=rotlg2ct(lat,lon)% ROTLG2CT Forms rotation matrix to convert from LG% (NEU) coordinate system to CT coordinate system.% If astronomic lat,lon input, then output is in% local astronomic system. Non-vectorized. See also% ROTCT2LG.% Version: 9 Jun 2000% Useage: R=rotlg2ct(lat,lon)% Input: lat - lat of local system origin (rad)% lon - lon of local system origin (rad)% Output: R - Rotation matrix to convert from LT (NEU) to CTR=zeros(3,3);R(1,1)=-sin(lat).*cos(lon);R(2,1)=-sin(lat).*sin(lon);R(3,1)=cos(lat);R(1,2)=-sin(lon);R(2,2)=cos(lon);R(3,2)=0;R(1,3)=cos(lat).*cos(lon);R(2,3)=cos(lat).*sin(lon);R(3,3)=sin(lat);
