CFTool generated code not working

Hi, i inputed in cftool the followings vectors Phi (1x14) Alfa (1x14) ef (14x14) so to obtain an interpolant surface (biharmonic(v4)). After this i clicked on "Generate code" obtaining function [fitresult, gof] = createFit4(Phi, Alfa, ef)

%CREATEFIT4(PHI,ALFA,EF) % Create a fit. % % Data for 'untitled fit 1' fit: % X Input : Phi % Y Input : Alfa % Z Output: ef % Output: % fitresult : a fit object representing the fit. % gof : structure with goodness-of fit info. % % See also FIT, CFIT, SFIT.

%% Fit: 'untitled fit 1'. [xData, yData, zData] = prepareSurfaceData( Phi, Alfa, ef );

% Set up fittype and options. ft = fittype( 'biharmonicinterp' ); opts = fitoptions( ft );

% Fit model to data. [fitresult, gof] = fit( [xData, yData], zData, ft, opts );

% Plot fit with data. figure( 'Name', 'untitled fit 1' ); h = plot( fitresult, [xData, yData], zData ); legend( h, 'untitled fit 1', 'ef vs. Phi, Alfa', 'Location', 'NorthEast' ); % Label axes xlabel( 'Phi' ); ylabel( 'Alfa' ); zlabel( 'ef' ); grid on view( -62.5, 18 );

When i try to run this file i have this message:

Error using createFit (line 23) Not enough input arguments.

Can anyone help me to understand what i'm missing? Thanks
