MATLAB: extract every nth element of vector

Question

Is there an easy way to extract every nth element of a vector in MATLAB? Say we have

x = linspace(1,10,10);

Is there a command something like

y = nth(x,3)

so that y = 3 6 9?

Cheers!

Answer 1

Try this:

x = linspace(1, 10, 10);
n = 3;
y = x(1 : n : end);  % => 1 4 7 10
y = x(n : n : end);  % => 3 6 9
