AQUILA is a MATLAB toolbox for the one- or twodimensional simulation of ％the electronic properties

function integral=intfield(field)

%INTFIELD integrate over whole structure
%
%integral=intfield(field)
%
%integrates the field over the whole area covered by the structure.
%Does basically the same as routine 'integrate'.
