Finding an initial point, then skipping a certain amount of points.

So here is what I've done so far. t=1:.5:50; randn('state',0); x=sin(2*pi*t); x=2*randn(size(t)); plot(x)

In order to create a random wave form. Now I wish to find the first point over 2, but then skip the next 5 points, regardless if its greater than 2 or not. Then I wish to skip the next five points again, and so forth until the end. This is a mere practice exercise for me, and I am still a learning student. Thanks in advance.

Are you provide x as example data? What is the point running x=sin(2*pi*t)?

x=2*randn(), x is never going to be greater than 2!

How does this question differ from: http://www.mathworks.com/matlabcentral/answers/14466-how-to-skip-certain-return-points-using-the-find-command

Because In that question, I wanted to find points greater than two, in this I want to find the first point over the threshold, then skip five points and find the next point regardless of its value.

Ok, now I get it.

Answer 1

[Walter Roberson]

wantedvalue = x(find(x>2,1,'first') + 5);

[Oleg Komarov]

Till the end:

x(find(x>2,1,'first'):6:end)

where for skipping I consider that you wanna leave five in between.
