I have No of turbines = [25,35,45,55,65];
I want No_of_turbines=25 35 45 55 65
25 35 45 55 65

turbines = [25,35,45,55,65];
how_often = 10;
No_of_turbines = repmat(turbines,how_often,1)
to get it ten times:
No_of_turbines =
25 35 45 55 65
25 35 45 55 65
25 35 45 55 65
25 35 45 55 65
25 35 45 55 65
25 35 45 55 65
25 35 45 55 65
25 35 45 55 65
25 35 45 55 65
25 35 45 55 65

Hey, I have one more quick question..
I have a array C=8760X1;
I want to make a array matrix of C=[C,C,C,C,C];
Can you help me with something other than hard coding like I mentioned above...?
Thanks in advance

Here it is with random values - just take the second argument of repmat:
C = rand(8760,1);
how_often = 5;
C_new = repmat(C,1,how_often)
