Vectors

Library of functions operating on vectors

Package Contents

toString

Convert a real vector in to a string representation

isEqual

Determine if two Real vectors are numerically identical

norm

Return the p-norm of a vector

length

Return length of a vector (better as norm(), if further symbolic processing is performed)

normalize

Return normalized vector such that length = 1 and prevent zero-division for zero vector

normalizeWithAssert

Return normalized vector such that length = 1 (trigger an assert for zero vector)

reverse

Reverse vector elements (e.g., v[1] becomes last element)

sort

Sort elements of vector in ascending or descending order

find

Find element in a vector

interpolate

Interpolate linearly in a vector

relNodePositions

Return vector of relative node positions (0..1)

Utilities

Utility functions that should not be directly utilized by the user

Library content

This library provides functions operating on vectors:

  • toString(v) - returns the string representation of vector v.
  • isEqual(v1, v2) - returns true if vectors v1 and v2 have the same size and the same elements.
  • norm(v,p) - returns the p-norm of vector v.
  • length(v) - returns the length of vector v (= norm(v,2), but inlined and therefore usable in symbolic manipulations)
  • normalize(v) - returns vector in direction of v with length = 1 and prevents zero-division for zero vector.
  • reverse(v) - reverses the vector elements of v.
  • sort(v) - sorts the elements of vector v in ascending or descending order.
  • find(e, v) - returns the index of the first occurrence of scalar e in vector v.
  • interpolate(x, y, xi) - returns the interpolated value in (x,y) that corresponds to xi.
  • relNodePositions(nNodes) - returns a vector of relative node positions (0..1).
