Hi there guys,
i got a problem that involves euclidean distance.
any ideas how to calculate the 3d dimensional distance between two points ?

This doesn't sound like a matlab problem to me.

EuclidDistance = sqrt((x1-x2)^2 + (y1-y2)^2 + (z1-z2)^2);

Where x1,y1,z1 are the 3D coordinates of point 1 and surprise surprise x2,y2,z2 are the 3D coordinates of point 2.

Hope that helps
