How to label specific increments

So this is my code:

x = linspace(0,2*pi,100);

y1 = cos(x).^2;

plot(x,y1,'--r')

ylim([-1 1])

xticks(0:pi/100:2*pi)

hold on

y2 = sin(x.^2);

plot(x,y2,'b')

hold off

legend('cos^2(x)','sin(x^2)')

xlabel('x')

ylabel('y')

title('Plot of y1=cos^2(x) and y2=sin(x^2)')

and i set it so there is a increment every pi/100, but i only want it to show a label for 0, pi/2, pi, 3pi/2, and 2pi. With the code I have set up right now, this is a label for every increment so the numbers at the bottom are jumbled together.

Set the ticks and minor ticks seperately

x = linspace(0,2*pi,100);
y1 = cos(x).^2;
y2 = sin(x.^2);

ax = axes();
hold on
plot(x,y1,'--r')
ylim([-1 1])
ax.XMinorTick ='on';
ax.XAxis.MinorTickValues = 0:pi/100:2*pi;
ax.XTick = (0:1/2:2)*pi;
ax.XTickLabel = {'0', '\pi/2', '\pi', '3\pi/2', '2\pi'};
plot(x,y2,'b')
hold off
legend('cos^2(x)','sin(x^2)')
xlabel('x')
ylabel('y')
title('Plot of y1=cos^2(x) and y2=sin(x^2)')

Try this:

x = linspace(0,2*pi,100);
y1 = cos(x).^2;
plot(x,y1,'--r')
ylim([-1 1])
xticks(0:pi/100:2*pi)
xticklabels({});
xtv = 0:pi/100:2*pi;
idx = find(ismembertol(xtv,[0, pi/2, pi, 3*pi/2, 2*pi], 0.001));
xtl = {'0','$\frac{\pi}{2}$','$\pi$','$\frac{3\pi}{2}$','$2\pi$'};
text(xtv(idx), min(ylim)*ones(size(idx)), xtl, 'Interpreter','latex', 'HorizontalAlignment','center', 'VerticalAlignment','top')
xlim([min(x) max(x)])
hold on
y2 = sin(x.^2);
plot(x,y2,'b')
hold off
legend('cos^2(x)','sin(x^2)', 'Location','SW')
xlabel('x')
ylabel('y')
title('Plot of y1=cos^2(x) and y2=sin(x^2)')
