%% Add Title and Axis Labels and Format Ticks % Plot $x\sin(y)-y\cos(x)$. 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. Repeat these steps for the y-axis. % % To use LaTeX in plots, see <docid:symbolic_ug.f2-234358>. syms x y fcontour(x*sin(y)-y*cos(x), [-2*pi 2*pi]) grid on title('xsin(y)-ycos(x) for -2\pi < x < 2\pi and -2\pi < y < 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); S = sym(ax.YLim(1):pi/2:ax.YLim(2)); ax.YTick = double(S); ax.YTickLabel = arrayfun(@texlabel, S, 'UniformOutput', false);
