Full Code
THIS is the code, but I cant seem to figure out why it shows (below) when I try to run the section
classdef SalsaSpectrum<handle
↑
Error: Illegal use of reserved keyword "classdef".
function handle = plot(obj, varargin)
% HANDLE = PLOT(obj,varargin)
%
% Plot a spectrum. The default syntax
%
% spec.plot()
%
% By default the velocity scale is used. Other options are
% 'pix' for indices and 'freq' for frequency.
%
% spec.plot('freq')
%
% If you have fitted Gaussians, they will also be
% displayed.
%
% If a second 'dummy' argument is supplied, and gaussians have
% been fitted, the individual Gaussians will be shown.
%
% spec.plot('vel', 'dummy')
clf
hold on
box on
%grid on
fff = 7;
set(gca, 'fontsize', fff)
ff = fff;
if ~isempty(varargin)
type = varargin{1};
else
type = 'vel';
end

If you're trying to run this by copying and pasting the code into the Command Window, that won't work. You need to construct the object by calling SalsaSpectrum with the appropriate inputs. Since the function's signature is:
function spec = SalsaSpectrum(fname)
you need to call SalsaSpectrum with one input, whatever the help text says fname should be, and one output.
