Windows 3D Scientific Calculator
Equation Solver, Regression, linear fit, curve fit, polynomial fit
The equation solver linear / curve fitting tool gives you 9 techniques to
choose from. (see bullets below)
The Polynomial Fit allows you to choose up to a 7th
order polynomial fit. The graphing tools are very powerful.
In the example below, you can see a 5th order polynomial fit equation on
some gravitational data of Mars. The graph updates REAL TIME as you
alter the parameters on the left.
The screen shot below shows
you three screens. The bottom one is the calculator screen, the 2nd
one is the data table that you populate with data from a text file or by
hand keying in the data. The top screen is the regression / fit
screen.
This screen will allow you to choose your plot colors and background
colors. You can also enlarge this screen to the full length of
your monitor.
