  • for i=1:1:360
th12=i/deg;
tth12(i)=th12; % tth12(i) indicates the i‟th element of the array.
th14=-1*(atan((0.08*cos(th12)-0.18-0.05*cos(th14))/(0.08*sin(th12)-0.05*sin(th14))));
tth14(i)=th14;*

th14=-1*(atan((0.08*cos(th12)-0.18-0.05*cos(th14))/(0.08*sin(th12)-0.05*sin(th14))));
This is the line where th14 is defined, but the right hand side is attempting to use th14 which does not exist since it has not been defined yet.
