Description

The Rotation Between 2 Vectors takes the input of two 3-by-1 vectors and returns a virtual world rotation (specified as a 4-element vector defining the axis and angle) that is needed to transform the first input vector to the second input vector.

Ports

Input

Port 1 — Input signal

3-element vector

The input signal is a 3-element vector whose elements correspond to its magnitudes along the $$\widehat{i},\widehat{j},\widehat{k}$$ unit vectors, respectively.

Data Types: double

Port 2 — Input signal

3-element vector

The input signal is a 3- element vector whose elements correspond to its magnitudes along the $$\widehat{i},\widehat{j},\widehat{k}$$ unit vectors, respectively.

Data Types: double

Output

Output 1 — Axis-Angle rotation

4-element vector

The output of the block is an axis-angle representation of the rotation needed to transform the first input vector to the second input vector.

Data Types: double
