11. This includes the possibility of defining a custom distance function and using existing indexes for acceleration. 12. The invariant interval can be seen as a non-positive definite distance function on spacetime. 13. In mathematics, a distance function or metric is a generalization of the concept of physical distance. 14. Let d \, be a distance function between a 3D line and a 3D point such that 15. Any call to above string distance function will supply two input strings and a maximum distance value. 16. This function " d " satisfies the properties of a distance function for a metric space. 17. Using a different distance function other than ( squared ) Euclidean distance may stop the algorithm from converging. 18. One of the definitions of skeleton using the distance function is as the ridges of the distance function. 19. One of the definitions of skeleton using the distance function is as the ridges of the distance function . 20. We want the family of affine distance functions to be a versal unfolding of the singularities which arise.
