We consider the pointwise and normwise approximation of function by some special matrix means of its Fourier series. The results corresponding to the theorem of Łenski and Szal in [5] and the results of Saini and Singh in [6] are shown. Some special cases as corollaries are also formulated. 2010 Mathematics Subject Classification: 42A24.
