Test Suite

Test Status Code Input and Output
1   Fail
u = [0.5 0.5 0];; v = [1 0 0]; angle_in_degrees = vector2angle(u,v) assert(strcmp(num2str(angle_in_degrees),'45'))

Dot indexing is not supported for variables of this type. Error in vector2angle (line 2) angle_in_degrees= acos(dot(u.v)/(abs(u)*abs(v)))*(180/pi); Error in Test1 (line 3) angle_in_degrees = vector2angle(u,v)

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

Dot indexing is not supported for variables of this type. Error in vector2angle (line 2) angle_in_degrees= acos(dot(u.v)/(abs(u)*abs(v)))*(180/pi); Error in Test2 (line 3) angle_in_degrees = vector2angle(u,v)

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

Dot indexing is not supported for variables of this type. Error in vector2angle (line 2) angle_in_degrees= acos(dot(u.v)/(abs(u)*abs(v)))*(180/pi); Error in Test3 (line 3) angle_in_degrees = vector2angle(u,v)
