Performs one-dimensional interpolation using the cubic Hermite interpolation method based on the lookup table defined by arrays of tabulated values of dependent and independent variables.
You can use the Evaluate Interpolating Polynomial node to find the interpolated values using the piecewise polynomial.
Tabulated values of the dependent variable.
Tabulated values of the independent variable. The length of X must equal the length of Y.
Values of the independent variable at which this node computes the interpolated values of the dependent variables.
Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.
Default: No error
Interpolated values that correspond to the independent variable values.
A cluster that contains the x domain endpoint values and coefficients of the piecewise interpolating polynomial.
The x domain endpoint values of the piecewise interpolating polynomial.
If x locations is of size N, the coefficients array should contain N - 1 rows of polynomial coefficients.
A 2D array of interpolating polynomial coefficients.
Row i of coefficients contains the coefficients for the interpolating polynomial between elements xi and xi + 1 of x locations.
Error information. The node produces this output according to standard error behavior.
The cubic Hermite interpolation method guarantees that the first derivative of the interpolant is continuous and sets the derivative at the endpoints in order to preserve the original shape and monotonicity of the Y data.
