ODEcalc 5.11.5
ODEcalc for Windows: An Ordinary Differential Equation (ODE) Calculator! State your equation and boundary or initial value conditions and it solves your problem. Plots solution y and derivative ydot versus x. A Fortran Calculus demo application.
Review by Phil Brubaker: Nice & easy ODE / BVP solution! Calculator also handy for interpolating. (5/5 - 17-Dec-2005)
 
CurvFit 5.11.5
A curve fitting program: Lorentzian, Sine, Exponential & Power series are available models to match your data. A Lorentzian series is recommended for real data especially for multiple peaked data. Another improved productivity example.
 
Rainbow 5.11.5
Find best Spectral Estimation Method for a Power Spectral Density plot. A menu of 10+ spectral estimators from Steve Kay's textbook 'Modern Spectral Estimation' 1988 is available to choose from. Some estimator results differ dramatically!
 
FC-Win 3.00
FC-Win (tm) is a front-end program for Fortran Calculus (tm). The Fortran Calculus (FC) language is for math modeling, simulation, and optimization. FC is based on Automatic Differentiation that simplifies computer code to an absolute minimum.
 
Match n Freq 5.11.5
Pulse shaping filter program that finds the pole-zero locations of a transfer function, H(s), for a matched filter. H(s) equals a -desired- signal (Yout) divided by a given input signal (Yin). Y's are in freq. Another improved productivity example.
 
Heat Transfer 3.00
Solves Heat Transfer BVP, IVP, IP problems. Source code + Output files are included. Calculus (level) Programming makes solving partial differential equations, ordinary differential equations and algebraic equations simple. You state the equations.
