how run generated code from apps

hello everybody

I've generated a simple code from curve fitting app by export code toolbar.

I've tried to past it in command windows but doesn't work.

function [fitresult, gof] = createFit(close)
%CREATEFIT(CLOSE)
%  Create a fit.
%
%  Data for 'untitled fit 1' fit:
%      Y Output: close from eurusd
%  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] = prepareCurveData( [], close );

% Set up fittype and options.
ft = fittype( 'poly1' );

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

% Plot fit with data.
figure( 'Name', 'untitled fit 1' );
h = plot( fitresult, xData, yData );
legend( h, 'close', 'untitled fit 1', 'Location', 'NorthEast', 'Interpreter', 'none' );
% Label axes
ylabel( 'close', 'Interpreter', 'none' );
grid on

You would want to save the code as a .m file. Then you can call the function with this line:

createFit(close)

Where close is your input

For example:

data = rand(14,1);
createFit(data)

ans = 
     Linear model Poly1:
     ans(x) = p1*x + p2
     Coefficients (with 95% confidence bounds):
       p1 =     0.01584  (-0.02285, 0.05453)
       p2 =      0.4963  (0.1669, 0.8258)

function [fitresult, gof] = createFit(close)
%CREATEFIT(CLOSE)
%  Create a fit.
%
%  Data for 'untitled fit 1' fit:
%      Y Output: close from eurusd
%  Output:
%      fitresult : a fit object representing the fit.
%      gof : structure with goodness-of fit info.
%
%  See also FIT, CFIT, SFIT.
