If z is omitted then the curve is only a 2D, but the equations are still valid._ r'T = ---- (Tangent)|r'|_ T'N = ---- (Normal)|T'|B = T x N (Binormal)k = |T'| (Curvature)t = dot(-B',N) (Torsion)
Example:theta = 2*pi*linspace(0,2,100);x = cos(theta);y = sin(theta);z = theta/(2*pi);[T,N,B,k,t] = frenet(x,y,z);line(x,y,z), hold onquiver3(x,y,z,T(:,1),T(:,2),T(:,3),'color','r')quiver3(x,y,z,N(:,1),N(:,2),N(:,3),'color','g')quiver3(x,y,z,B(:,1),B(:,2),B(:,3),'color','b')legend('Curve','Tangent','Normal','Binormal') Requirements: ยท MATLAB Release: R14
