ScalarInterpolation

Performs interpolation on input values using a specified dataset and interpolation method.

Takes an input value and produces an output by interpolating within a dataset according to the specified interpolation type. The component creates an interpolator object from the dataset and interpolation parameters, then applies this interpolator to map input values to output values through lookup and interpolation.

Usage

ScalarInterpolation(interpolation_type, filepath, independent_var, dependent_var)

Parameters:

Name	Description	Units	Default value
filepath	Dataset containing the data points to be interpolated	–
independent_var		–
dependent_var		–
interpolation_type		–

Connectors

• u - This connector represents a real signal as an input to a component (RealInput)

• y - This connector represents a real signal as an output from a component (RealOutput)
