QUAD_MESH_ORDER1 is a data directory which contains examples of files that define a quad mesh and an associated data value that is constant over each element of the mesh.
An order 1 quad mesh is a mesh of a 2D region based on quadrilaterals, with a piecewise constant value. An order1 quad mesh can be defined by three files:

FEM_IO, a FORTRAN90 library which reads or writes node, element and data files defining a finite element model.
FEM2D_PACK, a FORTRAN90 library which handles various tasks associated with 2D finite element meshes.
MESH_BANDWIDTH, a FORTRAN90 program which returns the geometric bandwidth associated with a mesh of elements of any order and in a space of arbitrary dimension.
MESH_DISPLAY_OPENGL, a C++ program which reads files defining a polygonal mesh and displays an image using OpenGL.
QUAD_MESH, a data directory which defines a format for storing meshes of quadrilaterals over a 2D region.
QUAD_MESH_ORDER1_DISPLAY, a MATLAB program which plots piecewise constant data associated with a mesh of quadrilaterals;
B5 displays the Hamming distance matrix for the binary codes for integers 0 through 5.
B15 displays the Hamming distance matrix for the binary codes for integers 0 through 15.
G5 displays the Hamming distance matrix for the Gray codes for integers 0 through 5.
G15 displays the Hamming distance matrix for the Gray codes for integers 0 through 15.
POOL is a simple rectilinear mesh using 28 points in a 7x4 grid, forming 18 elements, along with a value that we can think of as the depth of a swimming pool measured once in each element.
