Includes several applications: hopfviewer (viewing the Clifford torus), topeviewer (viewing 4D polytopes), and examples of user-defined parametric surfaces in 3D and 4D.
esve-1.0.3 Windows binaries
This paper is the basis for esve.
Find the automorphism group of a directed graph (possibly with colored vertices and arcs).
Find the symmetry group of a set of points in n-dimensional space. The permutation representation and the matrix representation are both available, including the eigenvalues and eigenvectors of each element.
Written in C++ with optional bindings to the ruby language.
Eigenvalues, eigenvectors, QR decomposition, singular value decomposition, etc.
Includes bindings to the LAPACK library.
This package is required for the spacegroup ruby script found in symfind.
Includes a description of each configuration's symmetry group (produced by symfind).
These may be viewed with topeviewer.
Includes a comprehensive test of general Dickson algebra identities as well as octonion and quaternion identities.
