Abstract
Barycentric formulas for the interpolation of a periodic functionf by a trigonometric polynomial have been given by Salzer [11] in the case of an odd number of arbitrary (interpolating) points and by Henrici [7] in the special case of equidistant points. We present here formulas for the interpolation with an even number of arbitrary points as well as simpler versions for an even or an odd functionf.
