How can I take the element of odd rows of an array (n rows, 1 column) and make a variable with all this elements?

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?

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

That´s right! Thanks Arif!

I was completely convinced that a for loop was the answer for my problem. I completely forgot this comand in Matlab.
