MATLAB: Is there any way to get results of curve fitting

curve fittinggraphplotplottingtoolbox

I have a graph created with curve fitting toolbox, but unfortunately i can not get results of this work each X values (1 to 80). How can i achieve this problem?

Thx,

Hi,

if you want to calculate the y-values for your 80 x values you can do so:

x = [1 2 3 10 20 80]
y = your_fitted_model(x)

The result is a vector containing the corresponding y-values for the given x-values.

Look the documentation for the topic Fit postprocessing for further Information.

MATLAB: How to access the result of Curve Fit App in the workspace

Hi,

when you are in the fitting app right click on the model you want to export:

then choose all options:

now you have the model, output and goodness in your workspace. To access the coefficients of the fitted model use:

>> coeffvals = coeffvalues(fittedmodel)
coeffvals =
      0.3768    1.4162    2.3424

To get some values from the goodness (for example the R-square value) use:

>> r_square = goodness.rsquare
r_square =
      0.9985

like shown here:
