The following is a list of C++ classes that I have written and am distributing by request to those that want them. Derivs Calculates the first derivative of a single parameter function by using Richardson Extrapolation. This class is a C++ translation of an Ada package given in the May 1991 issue of Computer Language . Fredholm2nd, Volterra2nd Classes for solving linear Fredholm and Volterra equations of the second kind. Kalman A general purpose Kalman filter class for optimal estimation of a dynamical system. KernelND, KernelNDAdaptive Classes for making kernel estimates of a PDF in N dimensions. There is both a fixed and an adaptive form. Model, Map, Ode, Runge A family of classes that allows the treatement of iterative maps and ordinary differential equations in a unified manner. The ordinary differential equations are solved using the class Runge which is a C++ adaptation of the code given in: W.H. Press, B.P. Flannery, S.A. Teukolsky and W.T. Vetterling, Numerical Recipes: The Art of Scientific Computing, Cambridge Univ. Press, New York, 1986 These classes were the example classes described in my recent Computer Language article: The Evolution of a C++ programmer, Computer Language, V. 9, No. 8, August 1992 MonteIntegrator, Quasi A Monte Carlo function integrator and its supporting random number generator. The random number generator is a quasi-random (as opposed to a pseudo-random) number generator, this gives the integrator a 1/N convergence rate (as opposed to 1/Sqrt(N) ). Can integrate functions up to 52 dimensions (this limit is due to the quasi random number generator). MCInv A library of routines that use Markov Chains for the estimation of: A single element of the inverse of a matrix. A given row of the inverse of a matrix. The solution of x = A x + f ( Matrix A, vectors x and f) for a given row. Based upon ACM Algorithm #166 Seawater, SeaParse A pair of classes for handling hydrographic data. Shared A Unix Shared Memory object base class. When this class is inherited by other classes then the derived class becomes a shared memory object that can be accessed by multiple processes. These objects can be persistant. SdeInt A Runge-Kutta like class for integrating systems of Stochastic Differential Equations. (includes the R250 random number generator). SimAnneal A general purpose Simulated Annealing class, for estimating optimum parameters of complicated functions or systems. (includes the R250 random number generator). Availability: These classes are available via anonymous FTP to taygeta.oc.nps.navy.mil the code is in the pub/c++ directory.
