Hello, I am trying to access the 30th row of a column vector, and then the 68th row, and then the 106th row, all the way up to 1474. So basically, row 30, and then a difference of 38 up to row 1474. I need to access these data in order to plot them. Thank you.

A(30:38:end)
%Example
A=rand(1474,1);
out=A(30:38:end);
plot(out)

Based on the wording of the question, it should probably be:
out=A(30:38:1474);
in case A has more than 1474 rows.
