Create a unit vector from two locations?

"A temporary second unit vector (j), was created from the second metatarsal head (MTH2) and CoM location, and divided by its norm."

Code:

MTH2 = [0.472 1.364 0.06]

CoM = [0.471 1.147 0.903]

UnitVector = CoM - MTH2 / norm(CoM - MTH2)

= [-0.069 0.42 0.83]

is this correct?

Answer 1

is this correct?

No.

MTH2 = [0.472 1.364 0.06]
CoM = [0.471 1.147 0.903]
UnitVector = (CoM - MTH2) / norm(CoM - MTH2) 

Answer 2

[David Hill]

MTH2 = [0.472 1.364 0.06];
CoM = [0.471 1.147 0.903];
UnitVector = (CoM - MTH2) / norm(CoM - MTH2) 

UnitVector = 1×3

-0.0011 -0.2493 0.9684
