Try this:
F = openfig('untitled.fig');
getF = get(F);
Lines = findobj(F, 'Type','Line');
for k = 1:numel(Lines)
X{k} = Lines(k).XData;
Y{k} = Lines(k).YData;
[Ymax,Idx] = max(Y{k});
FM{k,:} = [X{k}(Idx) Ymax Idx];
end
MagFreq = array2table(cell2mat(FM), 'VariableNames',{'Frequency','Magnitude','Index'})
producing:
MagFreq =
