Parameter Details

FILE. May contain a relative or absolute file path. Relative paths are relative to the directory specified by the DIR parameter.

INTERP. Specifies the method used to interpolate the data specified in the file.

INTERPDOM. Specifies the form in which the data is interpolated. When set to "Rectangular" the real and imaginary components of the data are interpolated separately. When set to "Polar" the interpolation is applied to the magnitude and angle of the data.

EXTRAP. Specifies the method used to extrapolate the data specified in the file. When set to "Interp Method", extrapolation uses the method specified by INTERP. When set to "Constant" the lowest value data point is used for any value below the range specified in the file, and the highest value data point is used for any value above it.

DIR. When FILE has a relative path, this parameter specifies to which directory the path is relative. The "Project" directory is where the project file is stored. The "Library" directory is specified in the Environment Options dialog box (choose Options > Environment Options). The "EM Models" directory location displays in the Directories dialog box (choose Help > Show Files/Directories).
