numerical solution of poisson equation using pascal language

Abstract

ABSTRACT The researcher targets to use the numerical solutions methods in solving the partial differential equations using the computer speed in the solution . The researcher has come to use the numerical solutions because the mathematical solutions needs great effort and an limited time. Moreover, there are some equations which can not be solved manually. Also the computer adds to the fact that it is very accurate in solving the equations, because of its great power in dealing with big numbers either integer or real. The research has included an example of aproblem that has been solved by the computer and compared with the manual solution. In additionto the above the research includes the decriesed of the number of the solution iterations.
