	x locations are 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.
	coefficients is a 2D array of interpolating polynomial coefficients. Row i of coefficients should contain the coefficients for the interpolating polynomial between elements xi and xi+1 of x locations.
	piecewise polynomial is a cluster that contains the x locations and coefficients of the piecewise interpolating polynomial. x locations are 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. coefficients is 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 returns any error or warning from the VI. You can wire error to the Error Cluster From Error Code VI to convert the error code or warning into an error cluster.

If x locations contains values x₀, x₁,…, x_n–1, row i of the coefficients 2D array corresponds to the coefficients for the interpolating polynomial between x_i and x_i+1.
