tet_mesh_quality, a MATLAB code which computes and prints a variety of quality measures for a given tet mesh of a set of points in 3D.
The tet mesh is defined by a node file containing the coordinates of nodes, and a tetra file containing quadruples of node indices.
The quality measures computed include:
Each quality measure is defined as the minimum of its value over each tetrahedron. The maximum and best possible value is 1, and the minimum and worst value is 0.

tet_mesh_quality is available in a C++ version and a FORTRAN90 version and a MATLAB version.
tet_mesh, a MATLAB code which carries out computations involving a tet mesh.
tet_mesh_boundary, a MATLAB code which returns the nodes and faces of the boundary of a tetrahedral mesh, which themselves form a 3d triangular mesh or "tri_surface".
tet_mesh_display, a MATLAB code which can read in the node and tetra files defining a tet mesh and display a wireframe image.
tet_mesh_l2q, a MATLAB code which converts a linear to quadratic tet mesh.
tet_mesh_tet_neighbors, a MATLAB code which computes the tetrahedral adjacency information.
tet_mesh_q2l, a MATLAB code which converts a quadratic to linear tet mesh.
tet_mesh_rcm, a MATLAB code which takes a tet mesh and relabels the nodes to reduce the bandwidth of the corresponding adjacency matrix.
tet_mesh_refine, a MATLAB code which can refine a tet mesh.
tet_mesh_volumes, a MATLAB code which computes the volume of each tetrahedron in a tet mesh.
