Arguments
Description
cftool opens the Curve Fitting Tool.
cftool(xdata,ydata) opens the Curve Fitting Tool with predictor data
specified by
xdata and response data specified by ydata. xdata and ydata must
be vectors of the same size.
Infs and NaNs are ignored because you cannot fit
data containing these values. Additionally, only the real component of a
complex value is used.
Remarks The Curve Fitting Tool is a graphical user interface (GUI) that allows you to
• Visually explore data and fits as scatter plots
• Graphically evaluate the goodness of fit using residuals and prediction
bounds
• Access GUIs for importing, preprocessing, and fitting data, and for plotting
and analyzing fits to the data
xdata A vector of predictor data.
ydata A vector of response data.
