Abstract: | We give a weighted Hermite-Fejér-type interpolatory method on the real line, which is a positive operator on “good” matrices.
We give an example on “good” interpolatory matrix by weighted Fekete points. To prove the convergence theorem we need the
generalization of “Rodrigues’ property”.
