Interpolates or extrapolates a function f at x given a set of n points (xi, yi), where f(xi) = yi, f is any function, and given a specific value.
If the number of elements in X is different from the number of elements in Y, this node sets interpolation value and interpolation error to NaN and returns an error.
Point at which the interpolation or extrapolation is performed.
If the value of x value is in the range of X, the node performs interpolation. Otherwise, the node performs extrapolation. If x value is too far from the range of X, the extrapolation error may be large. It is not a satisfactory extrapolation.
Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.
Default: No error
Interpolation of the function f at the point you specified.
An estimate of the error in the interpolation.
Error information. The node produces this output according to standard error behavior.
This node calculates interpolation value P(x), where P is the unique polynomial of degree n - 1 that passes through the n points (xi, yi).
