What Is Curve Fitting? Fitting Models to Data Made Easy with MATLAB
HTML-код
- Опубликовано: 24 авг 2024
- Curve fitting is a technique used to fit mathematical models to your data, helping you understand the relationship between different factors within your data set. Learn how to apply various curve fitting techniques using MATLAB® to wind turbine analysis with the aim of understanding how various factors influence power output.
With MATLAB, you can:
- Interactively fit curves and surfaces to your data using the Curve Fitter app: bit.ly/3xFxIVe
- Explore higher dimensional models through linear and nonlinear regression methods from Statistics and Machine Learning Toolbox™: bit.ly/441Cok0
- Optimize fitted models by specifying bounds and constraints with the functionality from Optimization Toolbox™: bit.ly/3Jh6s1w
- Incorporate your curve fits from the Curve Fitter app as a lookup table for use in Simulink®: bit.ly/3TX90XJ

my favorite is rational function fitting . i was amazed the first time is tried them
Which app was used for the non linear regression task?
Are you talking about the Curve Fitting App? www.mathworks.com/help/curvefit/curvefitter-app.html?s_eid=PSM_15028
Great question! We created the non-linear regression model using the Statistics & Machine Learning Toolbox. The visualization of the individual factors was done using the "plotSlice" method in that Toolbox.
