How to skip data point by plotting in 2D-curves surf-curve?

I would like to know how to skip data points by plotting 2d-curves?

For example, let:

x = 0:pi/100:2*pi;

y = sin(x);

plot(x,y);

What should I write if I want to display only every n-ten data point?

Thank you in advance Emerson

x = 0:pi/100:2*pi;
y = sin(x);
M=numel(x);
n=7;
index=1:n:M
plot(x(index),y(index));

Thank you Fangjun,

I used your suggestion and fixed my problem.

Do you know how to add the Minor Ticks from the command Line?

Currently, I'm editing the Major Ticks as follows:

set(gca)

set(gca,'XTick',0:1:7)

set(gca,'YTick',-1:0.5:1)

but I found no documentation for minor ticks.

I hope you are familiar with this subject

Thank you again for your help
