From: Alex Pereira on 1 Jul 2010 16:32 I've used the curve fitting GUI tool to setup some data, smooting and fitting options. Then, I've generated a M-File by using the option in the menu File of this tool. It generated a file that contain this piece of code below. When I try to using this function in any data, includig the one used to setup the data in the GUI, the following error message apears. ===== Error Message =========== ??? Undefined function or variable "sm_". Error in ==> createFit at 48 x_2 = (1:numel(sm_.y2))'; ===== End of Error Message ====== The 48h line is the one before last in the piece of code below. Can anyone help to fix this code ? Thank you very much, Alex ===== Piece of Code====== function createFit(r4) % Set up figure to receive datasets and fits f_ = clf; figure(f_); set(f_,'Units','Pixels','Position',[468 141 620 427]); legh_ = []; legt_ = {}; % handles and text for legend xlim_ = [Inf -Inf]; % limits of x axis ax_ = axes; set(ax_,'Units','normalized','OuterPosition',[0 0 1 1]); set(ax_,'Box','on'); axes(ax_); hold on; % --- Plot data originally in dataset "r4" x_1 = (1:numel(r4))'; r4 = r4(:); h_ = line(x_1,r4,'Parent',ax_,'Color',[0.333333 0 0.666667],...

The cfit version is 2.1 on Matlab 2009. I dont know how to produce such command line. Maybe it is not possible. But trying to learn it I've simplified the test by just creating a data test and a data smoothed test, and then saving it in a M-File. As a result this simplified test generate the same error. Studing the smooth function it can receive the y parameter or both y and x. When you provide only y data, it assumes the x data starts at 1 and increment one at each new y value. The code generated by the tool does not consider it. Then i fixed the generated code and it works fine. My correction code substitute the lines 48 and 49 by these: x_2 = (1:numel(sm_.y2))'; sm_.y2 = smooth(x_2,r4,5,'moving',0); Thank you very much. Alex |
