Optimized for the internet. Used for pre-algebra, geometry, trigonometry and general physics, through multivariable calculus, field theory, quantum mechanics and gravitation. Use time and color as extra dimensions (to create motion or encode momentum, for example). Use the scrollbar to vary parameters in realtime, to slice through graphs, or to vary surface transparency. DPGraph graphs functions, equations, conic sections, planes, spheres, toruses, parametric curves and surfaces, implicit equalities and inequalities, volume intersections, volumes of integration, surfaces of revolution, equipotential surfaces, vector fields, and much more, in rectangular, polar, cylindrical, or spherical coordinates.

The following link was added to the Math Archives' Other Software Sites page: Hilbert Class Library The Hilbert Class Library (HCL) is a collection of C++ classes representing basic mathematical objects such as vectors, linear and nonlinear operators, and functions. HCL also provides algorithms for optimization and linear algebra implemented in terms of these basic classes. The object oriented design of HCL permits algorithms to be coded at a natural level of abstraction, without reference to internal details of data structures and simulators. Because coordinate representations, data storage formats, and other domain-specific idiosyncrasies are not entangled in these implementations, the resulting code is reusable across applications of widely varying size and structure. The design of HCL also results in several very important capabilities, such as the ability to treat very large out-of-core data sets as vector objects, and to manipulate linear operators not defined explicitly by matrices, which distinguish HCL from other object oriented numerics libraries.
