# How to Normalize in Matlab

To normalise a vector is to convert it to a unit vector (a vector of magnitude 1) that points in the same direction. Normalisation is a common technique used to scale two data sets so they can be compared meaningfully.

To quickly normalise a vector in MATLAB, divide it by the result of the "norm" function (its magnitude).

Define the vector and store it in a variable with a command like this:

v = [1 4 17 2 9 5 5]

You can use any variable name in place of "v."

Divide your vector by its norm, and assign the result as the new value of the vector:

v = v/norm(v)

Check the magnitude of the vector with "norm," and see that its magnitude is now 1:
