ffunc.m

快速泊松方程求解--MATLAB Fast Poisson Solver in a Square

% function, f for poisson.m
%
% Assume x and y of same length.
% f is returned as a matrix, analyzed at all interior points of the grid
% if f = 0, make sure f is a matrix of zeros, the size of x, NOT JUST ONE VALUE = 0!
function f = ffunc(x,y)
f = exp(x.*y);
