Abstract
Some results on approximation of periodic functions are extended in two
directions: Improving the degree of approximation of periodic functions by sub-matrix
means of its Fourier series and such degree is applicable for a wider class of summbility
matrices in the sense of their entries in which class of sequences belongs to.
