Hallo all,
I want access to every element located in a odd row an make an array with all of them. For example:
A=(1:20)';
20 Rows and 1 column. So now I want in B every element from odd rows (1,3,5 so on).
For loop?

Ran in:
you don't need a loop
A=(1:20)';
oddrow=A(1:2:end)
oddrow = 10×1
1 3 5 7 9 11 13 15 17 19
