hi.i obtain mean of coloumn in matrix and curve fitting by cftool. then save generate code of it. but when I call it in the my code gives me an error message. What can I do?

% mean of matrix meanValue = mean(G);

x=1:1:47; y=meanValue; n=createFit(x,meanValue);

error is:

??? Error using ==> createFit Too many output arguments.

Error in ==> pixel at 35 n=createFit(x,meanValue);

thank you

在 MATLAB Online 中打开

Check the signature of the createFit function. Does it actually return something? i.e. if the signature is just:

function createFit(x,y)

then you will get the too many output arguments error since the above code is

n=createFit(x,meanValue);

i.e. the code is trying to get the return value of a function that does not return anything. There seems to be different versions of createFit on the MATLAB FileExchange and elsewhere too, so please verify that you are using the expected/correct version. I was able to reproduce your error using the code found at http://code.google.com/p/prosilica/source/browse/trunk/MATLAB/createFit.m?r=36
