Evaluate Interpolating Polynomial (G Dataflow)

Last Modified: March 15, 2017

Takes a cluster that contains the x domain endpoint values of the piecewise interpolating polynomial and a 2D array of interpolating polynomial coefficients and computes the dependent interpolated values at each independent variable value.

xi

Values of the independent variable at which this node computes the interpolated values of the dependent variables.

datatype_icon

piecewise polynomial

A cluster that contains the x locations and coefficients of the piecewise interpolating polynomial.

datatype_icon

x locations

The x domain endpoint values of the piecewise interpolating polynomial. If x locations is of size N, coefficients must contain N - 1 rows of polynomial coefficients.

datatype_icon

coefficients

A 2D array of interpolating polynomial coefficients. Row i of coefficients must contain the coefficients for the interpolating polynomial between elements xi and xi + 1 of x locations.

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

datatype_icon

yi

Interpolated values that correspond to the independent variable values.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.
