## description

**imra** is a package providing an implementation of de Boor-Ron
filtering (Tafti & al., 2006) for the following toy problem:

Two sets, **P0** and **P1**, of polygonal subdomains
on the plane are given. Also given are the values
corresponding to the averages of a scalar-valued function
**f** of two variables, over the polygons in **P0**.
A link is established between the sets **P0** and **P1** by
identifying, for each polygon **p** in **P1**, a subset **P0p** of
**P0** as the set of its neighbours.

With the above inputs, the programme assigns new values to
each polygon **p** in **P1**, by first finding the de Boor-Ron
polynomial that has the same averages as **f** over the
neighbours of **p** (i.e. the polygons in **P0p**), and then
*resampling* this polynomial by averaging it over **p**.

The actual task of finding the de Boor-Ron interpolant is performed by T.A. Grandine's MVP package, available from the netlib software repository. MVP itself depends on LAPACK. Brief installation instructions (including those for MVP and LAPACK) are provided in the included README file.
