loadEELS.m

function [si,en] = loadEELS(fnm)
%loadEELS loads an EELS spectrum image in dm3 format
% inputs:
%   fnm -- the name of the dm3 file to be loaded
% outputs:
%   si -- the 3D spectrum image, ordered [x,y,en]
%   en -- a vector of energy values corresponding to the energy axis.
%       (Warning!  this is often wrong and you may need to calibrate
%       yourself)
