Vector Blocks

The vector blocks include standard operations on vectors, such as the cross product and norm, as well as a rotation transformation for vectors. Translation is simply the sum of two vectors (using the Sum MATLAB Command Line Click to copy the following command line to the clipboard. Then paste it in the MATLAB Command Window: qc_open_matlab_help('sum'); block), and scaling is the element-wise product of two vectors (using the Product MATLAB Command Line Click to copy the following command line to the clipboard. Then paste it in the MATLAB Command Window: qc_open_matlab_help('product'); block) so no additional blocks are provided for translation and scaling. Simulink already provides a Dot Product MATLAB Command Line Click to copy the following command line to the clipboard. Then paste it in the MATLAB Command Window: doc('simulink/dot product') block as well.

Cross Product	Computes the cross product of two 3-vectors.
Norm	Computes the 2-norm of an arbitrary length vector or quaternion.
Normalize	Scales an arbitrary length vector or quaternion to a unit vector or unit quaternion, according to the 2-norm.
Norm Squared	Computes the square of the 2-norm of an arbitrary length vector or quaternion.
Vector from Skew Symmetric Matrix	Extracts a 3-vector from a skew-symmetric matrix.
Vector Rotation	Applies a fixed or variable rotation to a 3-element vector.
Vector to Skew Symmetric Matrix	Converts a 3-vector to a skew-symmetric matrix.
