چکیده
|
In this paper, first, a numerical method is presented for solving a class of linear fredholm integro-differential equation. the operational matrix of derivative is obtained by introducing hybrid third kind chebyshev polynomials and block-pulse functions. the application of the proposed operational matrix with tau method is then utilized to transform the integro-differential equations to the algebraic equations. finally, show the efficiency of the proposed method is indicated by some numerical examples.
