elem2BV in class Vec

compose

public Vec compose(int[] transfMap)

Compose this vector with given transformation. Always return a new vector

compose

public static Vec compose(TransfVec origVec,
          int[] transfMap,
          boolean keepOrig)

Compose given origVector with given transformation. Always returns a new vector. Original vector is kept if keepOrig is true.

Parameters:

origVec -

transfMap -

keepOrig -

Returns:

a new instance of TransfVec composing transformation of origVector and tranfsMap
