Webfitobject = fit (x,y,fitType) creates the fit to the data in x and y with the model specified by fitType. example. fitobject = fit ( [x,y],z,fitType) creates a surface fit to the data in vectors x , y, and z. example. fitobject = fit (x,y,fitType,fitOptions) creates a fit to the data using the algorithm options specified by the fitOptions object. Webft = fittype ( 'b*x^2+c*x+a' ); Get the coefficient names and order using the coeffnames function. coeffnames (ft) ans = 3x1 cell {'a'} {'b'} {'c'} Note that this is different from the order of the coefficients in the expression used to create ft with fittype. Load data, create a fit and set the start points.
