Like explained in the unit vectors article, you have to divide a vector by its magnitude to obtain the corresponding unit vector. This is exactly how it has to be done in MATLAB. Therefor the norm-function presented before is used. Corresponding to the example in the article, the unit vector be is computed based on vector b as follows:

Applying the norm-function to the new vector be proves that is has length 1. The described approach works for vectors of any dimension.
