place_header.m

非常好的数字处理教程

function place_header(figobject, handles)

	if isfield(handles, 'audiodata')
		headtext = [ handles.audiodata.filenamepath '  Duration: ' ...
						 num2str(length(handles.audiodata.data)/handles.audiodata.Fs) ' s'...  
						'  Fs: ' num2str(handles.audiodata.Fs) ' Hz'...
						'  Channels: ' num2str(handles.audiodata.channels)...
						'  Bits: ' num2str(handles.audiodata.nBits)];
	elseif isfield(handles, 'imagedata')
		headtext = [ handles.imagedata.filenamepath '  Size: ' ...
						 num2str(size(handles.imagedata.data,1)) 'x' ...  
						 num2str(size(handles.imagedata.data,2))];
	end

	set(figobject, 'Name', headtext);
