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:

*Hint: For detailed information about arithmetic operations in MATLAB please have a look on the article about simple arithmetic operations*

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