TRIANGULATION_NODE_TO_ELEMENT is a MATLAB program which reads datafiles describing a set of nodes, their triangulation, and the value of one or more quantities at each node, and outputs a file that averages the quantities for each element. This operation in effect creates an "order1" finite element model of the data.
The program reads three data files:
triangulation_node_to_element ( 'prefix' )where

TRIANGULATION_NODE_TO_ELEMENT is available in a C version and a C++ version and a FORTRAN77 version and a FORTRAN90 version and a MATLAB version.
MESH_TO_XML, a MATLAB program which reads information defining a 1D, 2D or 3D mesh, namely a file of node coordinates and a file of elements defined by node indices, and creates a corresponding XML file for input to DOLFIN or FENICS.
TRIANGULATION, a MATLAB library which carries out various operations on order 3 ("linear") or order 6 ("quadratic") triangulations.
TRIANGULATION_L2Q, a MATLAB program which reads information about a 3-node (linear) triangulation and creates data defining a corresponding 6-node (quadratic) triangulation;
TRIANGULATION_ORDER1_DISPLAY, a MATLAB program which plots piecewise constant data associated with a triangulation;
TRIANGULATION_ORDER3_CONTOUR, a MATLAB program which can display a contour plot of scalar data defined on a triangulation of order 3.
TRIANGULATION_ORDER6_CONTOUR, a MATLAB program which can display a contour plot of scalar data defined on a triangulation of order 6.
TRIANGULATION_Q2L, a MATLAB program which reads information about a 6-node (quadratic) triangulation and creates data defining a corresponding 3-node (linear) triangulation;
