This script gives the numirical solution of Laplace and Poisson equation Δ u(x,y)=f(x,y) where f(x,y)=0 for Laplace equation> The calculation is carried by iteration method

No of intervals = u(X0,Y)= u(Xn,Y)= u(X,Y0)= u(X,Yn)= the RHS f(x,y)= Lower X0=Lower Y0 = Upper Xn=Upper Yn = Output format :
