Interpolation and Regression

Summary

  • What is interpolation?
  • What is regression?
  • What are they useful for?
  • Numerical analysis in MATLAB
  • Plotting numerical models

What is interpolation?

  • Numerical model
  • Passes through all data points
  • polyfit: order of polynomial must be n-1

What is regression?

  • Numerical model
  • Does not have to pass through all data points
  • polyfit: pick order of polynomial (must be n-1 or less)

What are they useful for?

Numerical analysis in MATLAB

Plotting numerical models
