[xout,YOut,ZOut] = prepareSurfaceData(XIn,YIn,ZIn)如有必要，将数据转换为与fitfunction. The function transforms data as follows:

[xout,YOut,ZOut,WOut] = prepareSurfaceData(XIn,YIn,ZIn,赢)transforms data including weights (赢) for surface fitting with thefitfunction.

UseprepareSurfaceData如果您的数据不在列矢量形式中。例如，您有3个矩阵。您也可以使用prepareSurfaceDataif you have grid vectors, where长度（xin）= n，长度（yin）= m和size(ZIn) = [m,n]。您必须处理网格向量数据以与fit通过使用功能prepareSurfaceData。If you use the Curve Fitter app, you can select grid vector data and it automatically converts the data for you.

If your data is in a MATLAB^®表，您不需要使用prepareSurfaceData。You can specify variables in a MATLAB table as inputs to thefitfunction using the formtablename.varname。

When you generate code from the Curve Fitter app, the generated code includes a call toprepareSurfaceData(orprepareCurveDatafor curve fits). You can call the generated file from the command line with your original data or new data as input arguments, to recreate your fits and plots. If you call the generated file with new data, theprepareCurveDatafunction ensures you can use any data that you can fit in the Curve Fitter app, by reshaping if necessary and removingNaNs,infs, or the imaginary parts of complex numbers.
