  The concept of isogeometric analysis, whereby the parametric func- tions that
are used to describe CAD geometry are also used to approx- imate the unknown
fields in a numerical discretisation, has progressed rapidly in recent years.
This paper advances the field further by outlin- ing an isogeometric Boundary
Element Method (IGABEM) that only re- quires a representation of the geometry
of the domain for analysis, fitting neatly with the boundary representation
provided completely by CAD. The method circumvents the requirement to generate
a boundary mesh representing a significant step in reducing the gap between
engineering design and analysis. The current paper focuses on implementation
details of 2D IGABEM for elastostatic analysis with particular attention paid
towards the differences over conventional boundary element implementa- tions.
Examples of Matlab R{\deg} code are given whenever possible to aid
understanding of the techniques used.
