Graph plotter program plots 2D graphs from complex equations. The application comprises algebraic, trigonometric, hyperbolic and transcendental functions. EqPlot can be used to verify the results of nonlinear   more...regression analysis program.
Equation graph plotter gives engineers and researchers the power to graphically review equations, by putting a large number of equations at their fingertips. The program is also indispensable for students and teachers.
A flexible work area lets you type in your equations directly. It is as simple as a regular text editor. Annotate, edit and repeat your graphings in the work area. You can also paste your equations into the editor panel.
Example of mathematical expression:
5.22 - (2 * x) + square(x) + power(x;3) + power(2.55;4) - logbaseN(4;6.25)
Save your work for later use into a text or graphic file. Comprehensive online help is easily accessed within the program.
Features:
--------
*Scientific graphings
*Unlimited expression length
*Parenthesis compatible
*Scientific notation
*More than 35 functions
*More than 40 constants
*User-friendly error messages
*Simple mode (medium size on desktop)
*Paste expressions into EqPlot
*Online documentation
*All the benefits that Windows bestows, such as multi-tasking and print formatting are available  less

DataFitting program performs statistical regression analysis to estimate the values of parameters for linear, multivariate, polynomial, exponential and nonlinear functions. The regression analysis determines   more...the values of the parameters that cause the function to best fit the observed data that you provide. This process is also called curve fitting.
DataFitting gives engineers and researchers the power to find the ideal model for even the most complex data, by putting a large number of equations at their fingertips. DataFitting's built-in library includes a wide array of linear and nonlinear models from simple linear equations to high order polynomials. DataFitting has the following capabilities:
A 38-digit precision math emulator for properly fitting high order polynomials and rationals. A robust fitting capability for nonlinear fitting that effectively copes with outliers and a wide dynamic Y data range.
Once your data have been fit, DataFitting automatically sorts and plots the fitted equations by the statistical criteria of Standard Error. You can preview your graph and output publication-quality graphs in several different configurations. A residual graph as well as parameter output is generated for the selected fitted equation. Data, statistical and numeric summaries are also available from within the report-panel.  less
