%% Add Title and Axis Labels and Format Ticks % For $x$ from $-2\pi$ to $2\pi$, plot $sin(x)$. Add a title and axis % labels. Create the x-axis ticks by spanning the x-axis limits at % intervals of |pi/2|. Display these ticks by using the |XTick| property. % Create x-axis labels by using |arrayfun| to apply |texlabel| to |S|. % Display these labels by using the |XTickLabel| property. % % To use LaTeX in plots, see <docid:symbolic_ug.f2-234358>. syms x fplot(sin(x),[-2*pi 2*pi]) grid on title('sin(x) from -2\pi to 2\pi') xlabel('x') ylabel('y') ax = gca; S = sym(ax.XLim(1):pi/2:ax.XLim(2)); ax.XTick = double(S); ax.XTickLabel = arrayfun(@texlabel,S,'UniformOutput',false);
