Simulators, graphing and signal analysis in a spreadsheet
Every model is open: the equations are formulas you can read, change and extend, with sliders for the constants.
What you can do
Your own equations
Write your own differential equations and constants, and watch the results update as you move the sliders.
Graph Lab
Plot several equations with sliders, find zeros and peaks, and draw surfaces z = f(x, y), spheres, circles and other shapes.
Signal Lab
Fourier spectrum, filters, Laplace and Z transforms, transfer functions and unit conversions.
Graph Equation
Plot one formula in x with its slope and area under the curve.
All in the workbook
Results land in cells, so you can chart them, analyse them and save them as .xlsx.
Questions
Do I need to install anything?
No. The labs run in the browser inside the spreadsheet.
Can I edit the models?
Yes. Every model is made of formulas and constants you can change.
