prepareSurfaceData - Prepare data inputs for surface fitting

Syntax

Description

[XOut, YOut, ZOut] = prepareSurfaceData(XIn, YIn, ZIn) transforms data, if necessary, for surface fitting with the fit function. The function transforms data as follows:

• For table data, transform row (YIn) and column (XIn) headers into arrays YOut and XOut that are the same size as ZIn. Warn if XIn and YIn are reversed.

• Return data as columns regardless of the input shapes. Error if the number of elements do not match. Warn if the number of elements match, but the sizes are different.

• Convert complex to real (remove imaginary parts) and warn of this conversion.

• Remove NaN or Inf from data and warn of this removal.

• Convert nondouble to double and warn of this conversion.

[XOut, YOut, ZOut, WOut] = prepareSurfaceData(XIn, YIn, ZIn, WIn) transforms data including weights (WIn) for surface fitting with the fit function.
