Fit a second order polynomial to the data
WebTo fit a second-order polynomial, we need to find coefficients a2, a1, and a0 in the following equation: y = a 2 x 2 + a 1 x + a 0 We can use the given values of x and y to create a system of equations and solve for the coefficients. WebA line will connect any two points, so a first degree polynomial equation is an exact fit through any two points with distinct x coordinates. If the order of the equation is …

To fit polynomials of different degrees, change the fit type, e.g., for a cubic or third-degree polynomial use 'poly3'. The scale of the input, cdate, is quite large, so you can obtain better results by centering and scaling the data. To do this, use the 'Normalize' option.
