In geometry, a simplex (plural: simplexes or simplices) is a generalization of the notion of a triangle or tetrahedron to arbitrary dimensions. The simplex is so-named because it represents the simplest possible polytope in any given dimension. For example, • a 0-dimensional simplex is a point, • a 1-dimensional simplex is a line segment, Webbfunctions, mathematics of ﬁnance, matrix algebra, quadratic and polynomial functions, simplex and computer solution method, systems of linear equations tests for middle school revision guide.
