Summary: In a recent paper, S. Lal
and K. N. S. Yadav
[Bull. Calcutta Math. Soc. 93, No. 3, 191–196 (2001; Zbl 1032.42003
)] obtained a theorem on the degree of approximation for a function belonging to a Lipschitz class using a triangular matrix transform of the Fourier series representation of the function. The matrix involved was the product of
, the Cesàro matrix of order one, with
, the Euler matrix of order one. In this paper we extend this result to a much wider class of Hausdorff matrices.
