Takes the piecewise interpolating polynomial and computes the interpolated values at each independent variable value.

connector_pane_image
datatype_icon

xi

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

datatype_icon

piecewise polynomial

Piecewise interpolating polynomial.

datatype_icon

x locations

Endpoint values of the x domain.

datatype_icon

coefficients

Coefficients of the interpolating polynomial.

Row i of coefficients contains the coefficients for the interpolating polynomial between elements x i and x i + 1 of x locations. If x locations is of size N, coefficients contain N - 1 rows of polynomial coefficients.

datatype_icon

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 xi.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

Desktop OS: Windows

FPGA: Not supported

Web Server: Not supported in VIs that run in a web application
