Specify which data form to be outputted.

Option list:

  • xyz{0}:XYZ Data
    Output interpolated contour values in XYZ data form.
  • mat{1}:Matrix
    Output interpolated contour values in matrix form.
Output oz

Output

XYZRange

[<new>]<new>!(<new>,<new>,<new>)
specifying a worksheet for the output gridding data. See the syntax here.
Output Matrix om

Description

This X-Function is used to create gridding data from XYZ contour/XYZ worksheet data.

Algorithm

The values for the specified grid points are computed by triangulation and line interpolation as described in algorithm section. Note that contour values outside input data range will be set as missing values.
