  Present work presents a code written in the very simple programming language
MATLAB, for three dimensional linear elastostatics, using constant boundary
elements. The code, in full or in part, is not a translation or a copy of any
of the existing codes. Present paper explains how the code is written, and
lists all the formulae used. Code is verified by using the code to solve a
simple problem which has the well known approximate analytical solution. Of
course, present work does not make any contribution to research on boundary
elements, in terms of theory. But the work is justified by the fact that, to
the best of author's knowledge, as of now, one cannot find an open access
MATLAB code for three dimensional linear elastostatics using constant boundary
elements. Author hopes this paper to be of help to beginners who wish to
understand how a simple but complete boundary element code works, so that they
can build upon and modify the present open access code to solve complex
engineering problems quickly and easily. The code is available online for open
access (as supplementary file for the present paper), and may be downloaded
from the website for the present journal.
