MEDIT_IO <br> Reading and Writing MEDIT Mesh Files
</h1>
<hr>
<p>
<b>MEDIT_IO</b>
is a MATLAB library which
can read or write files used by the MEDIT program, which can be used to
define the a mesh associated with the finite element method (FEM)
in 2D or 3D, using triangles, quadrilaterals, tetrahedrons or hexahedrons.
