If y is not a vector, then polyfit converts it into a column vector y(:). Data Types: single | double Complex Number Support: Yes n— Degree of polynomial fit positive integer scalar Degree of polynomial fit, specified as a positive integer scalar. n specifies the polynomial power of ...
If init_sys is not a polynomial model with the ARMAX structure, the software first converts init_sys to an ARMAX model. armax uses the parameters of the resulting model as the initial guess for estimating sys. If opt is not specified and init_sys was obtained by estimation, then the ...
Use sixth degree polynomial to estimate the radial distortion of a lens. 此设置仅适用于大视场相机。 使用六次多项式来估计透镜的径向畸变。 综上所述: 对于一般的相机选择2 Coefficients选项即可,对于大视场相机则选择3 Coefficients选项。 1 2 3

same since the last of the 5 term is zero, regardless, I have tried 3 terms, got the relative error, and it is soo similar to having 4 terms. The difference is so big between the function and the taylor polynomial when x=0 or any other number, that is not even an approx...
