| چکیده | ||
| This paper tries to provide an attractive framework based on Block-Pulse functions for numerical solution of a system of two-dimensional Volterra integral equations of the second kind. These types of systems are created through the modeling of physics or engineering phenomena. By constructing operational matrices based on Block-Pulse functions and reduction of variables, a simpler algorithm is built. The block-pulse method is affordable because it converts algebraic systems to a matrix system and reduces the amount of computation. Some numerical examples and error analysis which are in detail support the method. | ||
