ODEcalc

Differential equation solver 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. Solves most Boundary Value Problems (BVP) and Initial Value Problems (IVP) for Nth order ODE. ODE may be non-linear, implicit, and any order. Source code included ... it''s short! Great teaching tool! A Fortran Calculus demo appl.

DreamCalc Graphing Calculator

DreamCalc is the smarter alternative to a hand-held Graphing Calculator for your PC or laptop! You'll get the intuitive feel and productivity of using a professional hand-held, but one which adapts to your way of working. Select from Reverse Polish Notation or two styles of algebraic input, and with the optional ability to run in your Windows system tray--DreamCalc will always be there whenever you need to reach for a calculator.

Midget

A calculator with very small screen footprint but lots of power! Just type in any expression, like "2+3.9/7.1-3 sqr 5", and hit Enter; then modify it and evaluate again at will, without re-entering everything. 18 digits of precision, 30 functions, 12 memories (variables), fractions, unit conversion, adjustable display format and precision, deg/min/sec, save and restore, on-line help; this program is loaded!

Matrix Calculator

Matrix calculator operations include: transpose, invert, scale, compute determinant and trace, adjoint, multiply, add, and subtract. Matrices can be saved to a text file for future sessions. A delimiter can be specified to separate elements of the matrix in the input or output text file. A help file is provided with examples. The precision of the computed matrix can be determined interactively before it is saved. Matrix Calculator is licensed as shareware and filed in business calculators, converters section.

SLAE Solver

SLAE SOLVER allows to find on a personal computer high accuracy solutions of linear algebraic systems with N equations, where N may reach hundreds or thousands. This education software is categorized under advanced calculators.

Statmaster

Many scientific and engineering programs generate numeric output which needs to be presented graphically. Statmaster is a simple way to do that, reading a text file with data arranged in a space-separated table, and drawing up to 16 pages of histograms and XY plots, up to 64 graphs per page. The way in which the data is presented is defined in a simple Windows inifile, and most graph attributes can be adjusted as needed.

Kalkulator

The most powerful Sci/Eng calculator for Windows. Expression evaluation, 18 digits of precision, variables, 100 functions, unit conversion, polynomial roots, interpolation, polynomial regression, linear algebra, numerical integration and differentiation, systems of linear, non-linear and differential equations, multi-argument functon optimization and fitting, curve, point and histogram graphs, statistical operations, computer math (bin/oct/hex).

Abacus Math Writer

MathWriter is a java stand-alone program that allows for the production of, Mathematical, Scientific and Engineering equations and formulae. Schoolteachers and Lecturers will find MathWriter useful for producing notes, reports and test papers. The program is designed so that an expression may be written on the screen and then translated into a bitmap image of required size. This image may then be subsequently imported to Microsoft Word.

DreamCalc Scientific Calculator

DreamCalc is the smarter alternative to a hand-held Scientific Calculator for your PC or laptop! You'll get the intuitive feel and productivity of using a professional hand-held, but one which adapts to your way of working. Select from Reverse Polish Notation or two styles of algebraic input, and with the optional ability to run in your Windows system tray--DreamCalc will always be there whenever you need to reach for a calculator.
