not reading the data.

running the code as following to fit 5 Lorentzian peaks.

xdata = pixelPeakData{p,1}';
ydata = pixelPeakData{p,2}';
% Fit = PeakFit();
Fit = PeakFit([xdata; ydata], ...
                'Window', [-5, 5], ...
                'NumPeaks', 5, ...
                'PeakShape', 1, ... % 'Lorentzian'
                'CenterStart', [-3.5, -1.6, 0, 2, 3.5], ...
                'CenterLow', [-4, -1.7, -1, 1, 3.4], ...
                'CenterUp', [-3, -1.5, 1, 2, 3.6], ...
                'BaselinePolyOrder', 1 ...
                );

But it gives the followoing error.

Error in PeakFit (line 314)
            if k <= N && isrealmatrix(varargin{k})
Error in peakfitting_toil (line 8)
Fit = PeakFit([xdata; ydata], ... 

xdata, ydata both are 1x30 double

Thank you for posting the issue. Try the second syntax: obj = PeakFit(XData, YData, ... Name-Value ...). Cheers.
