[Vxl-users] Vnl using non-vnl matrices/vectors?

[Kris T. <kri...@cs...>]

Hi

I'm new to vxl, but am wondering if it would be possible to use some of the
VNL routines with my own vector and matrix classes. I know, I'm asking too
much...

I realise that this will involve some work but would like to ask for some
suggestions. 

I suppose the easiest way to go would be to make sure that my classes
provide the same interface as vnl_vector and vnl_matrix, and then typedef
vnl_vector etc. Somewhat cleaner would be to derive vnl_vector from my
classes from my own classes. Or some wrapper classes as suggested in
Numerical Recipes for C++ 
(see http://www.numerical-recipes.com/cpppages/chap1sel.pdf p.29 et al)

A longer route (but in the end more satisfying) would be to template the vnl
routines in terms of vector and matrix classes (which still need to have the
correct interface). A lot of trouble with instanstations then of course.


Why? Obviously because I have a lot of work done using my own classes.
