1   Pass
u = [0.5 0.5 0];; v = [1 0 0]; angle_in_degrees = vector2angle(u,v) assert(strcmp(num2str(angle_in_degrees),'45'))

a = 0.5000 angle_in_degrees = 45 angle_in_degrees = 45

2   Pass
u = [0 0 1]; v = [1 0 0]; angle_in_degrees = vector2angle(u,v) assert(strcmp(num2str(angle_in_degrees),'90'))

a = 0 angle_in_degrees = 90 angle_in_degrees = 90

3   Pass
u = [0 0.8 1]; v = [1 0.3 0]; angle_in_degrees = vector2angle(u,v) assert(strcmp(num2str(round(angle_in_degrees)),'80'))

a = 0.2400 angle_in_degrees = 80 angle_in_degrees = 80
