Strided() [3/4]

aff::Strided::Strided ( const TIndexVec &  first, const TIndexVec &  last, const Tsubscript &  shift = 0  )

explicit

construct Fortran layout to given first and last index

construct do given first and last index

Parameters

first	vector of first index value in each dimension
last	vector of last index value in each dimension
shift	defines offset shift (i.e. first element accessed in memory representation)

This constructor together with the aff::Strided::shrink() function is used by aff::Shaper in aff::Shaper::operator Tshape () to create a strided shape.
