Let 1 be n+2 distinct points on the real line and let us denote the corresponding real numbers, which are at the moment arbitrary, by 2 The problem of Hermite-Fejér interpolation is to construct the polynomials which take the values (2) at the abscissas (1) and have preassigned derivatives at these points. This idea has recently been exploited in a very interesting manner by P. Szasz [1] who has termed qua si-Hermite-Fejér interpolation to be that process wherein the derivatives are only prescribed at the points x1, x2, ..., xn and the points -1, +1 are left out, while the values are prescribed at all the abscissas (1).
