Like explained in the [[Unit vectors|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.

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.
