This example calculates the angle between two vectors, using two different methods. The first method uses the following equation:
cos(theta) = ((Vector 1) . (Vector 2)) / (||Vector 1|| X ||Vector 2||) where the . (dot) is the dot product between the vectors and ||Vector|| = the magnitude of the vector.
The second method uses the complex LabVIEW math routines to calculate each vector phase. To compute theta, the VI calculates the difference between the phase of each vector.
