Hi, being very newish to Matlab I am trying to solve a simple problem to begin with, and advance from there. I have 2 sets if data (named x and y in workspace). When I use curve fitting tool to fit the data, it works fine, but if I use the script below in .m file, I get error saying more input arguments are needed to run.
ft = fittype ('poly4'); [xdata, ydata] = prepareCurveData(x,y); c = fit(xdata,ydata,ft);
I have tried the fit from curve fitting toolbox and using generate code function and I get the same error. What am I missing here?
Any help is appreciated.

'Generate code' usually returns a function and not a scrip. Is it possible that you are not calling the function with the right arguments?
Could you paste the exact error message from the command line?
Also, could you run the following and see if it works?
>> x = rand(10,1); >> y = rand(10,1); >> ft = fittype ('poly4'); [xdata, ydata] = prepareCurveData(x,y); c = fit(xdata,ydata,ft);
