Polyfit matlab8/28/2023 ![]() ![]() ![]() The polynomial coefficients are returned in a row vector. The corresponding polynomial coefficients to be used or ignored. If n is a logical vector, it is used as a mask to selectively force N that minimizes the least-squares-error of the fit to the points Return the coefficients of a polynomial p( x) of degree P = polyfit ( x, y, n) = polyfit ( x, y, n) = polyfit ( x, y, n) Is necessary to fit the polynomial in a least-squares sense, which just ![]() Wants to fit a low-order polynomial to data. To avoid a highly fluctuating polynomial, one most often To the functions described in the aforementioned chapter, is to fitĪ single polynomial, or a piecewise polynomial (spline) to some givenÄata points. Most of which are described in Interpolation. Octave comes with good support for various kinds of interpolation, Next: Miscellaneous Functions, Previous: Derivatives / Integrals / Transforms, Up: Polynomial Manipulations
