Approximation by matrix transform means with respect to the Walsh system in Lebesgue spaces
In this paper, we improve, complement and generalize (from Nör\-lund to matrix transform means) a result of Móricz and Siddiqi \cite{MS} and some statements of Areshidze and Tephnadze \cite{AT}, and (from $T$ (weighted) to matrix transform means) Anakidze, Areshidze, Persson and Tephnadze \cite{AAPT}.
