Sci-eval — scientific data fitting, ODE solving & plotting

A free online platform for scientists and engineers to perform least squares curve fitting, solve systems of ordinary differential equations (ODEs), and plot experimental data.

  • Define your functions and ODE systems

    Write arbitrary mathematical models and systems of ordinary differential equations (ODEs) using Python's SymPy library.

  • Least squares fitting of your experimental data

    Fit your data with robust least squares optimization. Fix or free your parameters, set bounds, or fit on a log scale, then plot the results.

  • Share with other researchers

    Add the DOI of your publication and make your fit-model available to everyone.

Figure Studio
