distance between two vertices

How I can compute the distance between two vertices (point)

vertex1 = (x,y,z) vertex2 = (x,y,z)

Answer 1

[Andrei Bobrov]

Pythagorean

d = sqrt(sum((vertex1-vertex2).^2))

hypot()

k = vertex1-vertex2;
d = hypot(hypot(k(1),k(2)),k(3));

use norm()

d = norm(vertex1-vertex2,2);

use dist from Neural Network Toolbox

d = dist([vertex1;vertex2]')

use pdist from Statistics Toolbox

d = pdist([vertex1;vertex2])

Sometimes this is fast for row vectors: v = vertex1 - vertex2; d = sqrt(v * v');

Wouldn't the Pythagorean theorem or hypot() work?
