How to represent set?

Newbie here try to implement an algorithm in MATLAB but do not know how to represent set.

For example, when initiate the algorithm, i need to:

Set .

And .

I tried this

C{0} = []  % Error: Array indices must be positive integers or logical values.
C{1} = 1:N 

I am not sure how to set empty set and if I am doing right with C_1.

Can anyone help me?

Thanks!

In MATLAB, the index starts from 1. So the first line should be

C{1} = [];

The variable should also be defined before its use. So you need to specify define

N = 10;
C{2} = 1:N;
