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;
