error in figure print
显示 更早的评论
I am trying to run this code but i get error message
% if figname set, use it; otherwise the data file name
if isfield(cfg, 'figname') && ~isempty(cfg.figname),
set(gcf, 'Name', sprintf('Fig.%d: %s', gcf, cfg.figname), 'NumberTitle', 'off');
elseif isfield(cfg, 'datafile') && ~isempty(cfg.datafile),
slashpos = find(cfg.datafile == '/' | cfg.datafile == '\', 1, 'last');
if ~isempty(slashpos), cfg.datafile = cfg.datafile(slashpos+1:end); end;
set(gcf, 'Name', sprintf('Fig.%d: %s', gcf, cfg.datafile), 'NumberTitle', 'off');
else % shorten the figure name anyway
set(gcf, 'Name', sprintf('Fig.%d', gcf), 'NumberTitle', 'off');
end;
what does this mean?
"Error using sprintf Function is not defined for 'matlab.ui.Figure' inputs"

You have two calls to sprintf in which you ask to format gcf
Change those two gcf to be double(gcf)

cfg = [];
% if figname set, use it; otherwise the data file name
if isfield(cfg, 'figname') && ~isempty(cfg.figname),
set(gcf, 'Name', sprintf('Fig.%d: %s', double(gcf), cfg.figname), 'NumberTitle', 'off');
elseif isfield(cfg, 'datafile') && ~isempty(cfg.datafile),
slashpos = find(cfg.datafile == '/' | cfg.datafile == '\', 1, 'last');
if ~isempty(slashpos), cfg.datafile = cfg.datafile(slashpos+1:end); end;
set(gcf, 'Name', sprintf('Fig.%d: %s', double(gcf), cfg.datafile), 'NumberTitle', 'off');
else % shorten the figure name anyway
set(gcf, 'Name', sprintf('Fig.%d', double(gcf)), 'NumberTitle', 'off');
end
get(gcf,'Name')
