solar position calculator
function [angles,projection] = solarPosition(datetime,latitude,longitude,time_zone,rotation,dst)
%SOLARPOSITION Calculate solar position using most basic algorithm
% This is the most basic algorithm. It is documented in Seinfeld &
% Pandis, Duffie & Beckman and Wikipedia.
%
% [ANGLES,PROJECTION] = SOLARPOSITION(DATE,TIME,LATITUDE,LONGITUDE,TIME_ZONE)
% returns ZENITH & AZIMUTH for all DATE & TIME pairs at LATITUDE, LONGITUDE.
% ANGLES = [ZENITH,AZIMUTH] and PROJECTION = [PHI_X, PHI_Y]
% PHI_X is projection on x-z plane & PHI_Y is projection on y-z plane.
% DATETIME can be string, vector [YEAR, MONTH, DAY, HOURS, MINUTES, SECONDS],
