How to Find Vector Norm

In Linear Algebra, a norm is a way of expressing the total length of the vectors in a space. Commonly, the norm is referred to as the vector’s magnitude, and there are several ways to calculate the norm.

How to Find the 𝓁1 Norm

The 𝓁1 norm is the sum of the vector’s components. This can be referred to as a taxicab norm since it is equal to the path a taxi might take to get from the origin point to the vector’s coordinates.

𝓁1 Norm Formula

Since the 𝓁1 norm is the sum of the component’s absolute values, the formula for the 𝓁1 norm is:

𝓁1 = |x| + |y| + |z|

Thus, the 𝓁1 norm is equal to the absolute value of x plus the absolute value of y plus the absolute value of z.

How to Find the 𝓁2 Norm

The 𝓁2 norm is sometimes referred to as the Euclidean norm, and you can find it using the vector magnitude formula.

𝓁2 Norm Formula

The 𝓁2 norm is equal to the square root of the sum of the squares of each component of the vector. The formula looks like this:

|a|= x² + y² + z²

Thus, the 𝓁2 norm of a vector is equal to the square root of the sum of the square of each of the vector’s components x, y, and z.

How to Find the 𝓁 Norm

The 𝓁 norm is equal to the absolute value of the largest magnitude of each of the vector’s components. Thus, the 𝓁 norm is equal to the largest component value in the vector.
