%% Include Superscripts and Annotations in Graph Text % Create a line plot and add a title and axis labels to the graph. Display % a superscript in the title using the |^| character. The |^| character % modifies the character immediately following it. Include multiple % characters in the superscript by enclosing them in curly braces |{}|. % Include the Greek letters $\alpha$ and $\mu$ in the text using the TeX % markups |\alpha| and |\mu|, respectively. % t = 1:900; y = 0.25*exp(-0.005*t); figure plot(t,y) title('Ae^{\alphat} for A = 0.25 and \alpha = -0.0005') xlabel('Time \musec') ylabel('Amplitude') %% % Add text at the data point where |t = 300|. Use the TeX markup |\bullet| % to add a marker to the specified point and use |\leftarrow| to include an % arrow pointing to the left. By default, the specified data point is to % the left of the text. txt = '\bullet \leftarrow 0.25t e^{-0.005t} at t = 300'; text(t(300),y(300),txt)
