startpotential.m

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

function startpotential(startpot)

%STARTPOTENTIAL use non-zero startpotential
%
%startpotential(phi)
%
%Allows you to specify a potential for starting the iteration
%different form the default flat (all zero) potential.
%The field phi must have the correct size and can be obtained
%e.g. from a previous run of a similar structure. Using an
%external startpotential also means, that the Schroedinger solver
%is switched on immediately at the beginning of the iteration.
