A metric is a function that give the distance between any two elements of a space.
🔗
A metric may be induced from a norm as shown at: Section 1.3.2. "Metric induced from a norm".
🔗
Because a norm can be induced by an inner product, and the inner product given by the matrix representation of a positive definite symmetric bilinear form, in simple cases metrics can also be represented by a matrix.
