General Parameter Estimation

Application ID: 86541

This app demonstrates the following:

  • Importing measured data from a text file or use built-in functionality for data generation
  • Automatically change solver options based on the input
  • Dynamically update the equation display

The app can be used to estimate parameters in models without any physics. Data can be imported from a file or the built-in functionality for data generation can be utilized.

The models include linear, quadratic, sigmoid, sloped Gaussian, and a custom model with up to 5 parameters.

The Levenberg-Marquardt solver computes confidence intervals for the estimated parameters, while the other solvers (MMA, SNOPT, and BOBYQA) allow for specification of parameter bounds. MMA and BOBYQA allow for minimization of the maximum square instead of the sum.

This application example illustrates applications of this type that would nominally be built using the following products:
