In the above example, the optimal choice for the degree of the polynomial approximation would be between three and six. However, there is an alternative to manually selecting the degree of the polynomial: we can add a constraint to our linear regression model that constrains the magnitude of the coefficients in the regression model....

Find the polynomial from the roots If you know that the roots of a polynomial are -4, 3, -2, and 1, then you can find the polynomial (coefficients) this way: r = [-4 3 -2 1];

## How To Find Polyfit Coefficents

### Until you find a proper function out there to do this for you, I think the best bet right now is to write your own function to use the p.cN_N coefficients to calculate your peak, similar to above. As long as you always use Polynomial2D with n=2 , the equations should hold.

- This is a third post in the polynomial fitting series demonstrating how to perform polynomial fitting using LU decomposition in C#. For more information on polynomial fitting please refer to the pervious post polynomial fitting in C++.
- The text description "poly can be used to find out the coefficients" does not allow to estimate, if you made a mistake when calling poly(). Currently I find in your question: a = [2, 4, 6, 8];

- The function polyfit calculates the coefficients of the fitted polynomial, and the function polyval determines the values of that polynomial at the desired data points. To use a polynomial of a higher degree to fit the data, just change the third parameter of polyfit to the degree of the polynomial.
