I’m a little confused about the parameter named ‘n’ of rotated_lorentz(n).

For example,

cvx_begin

variable x(10);

variable y(10);

variable z(10);

minimize(sum(x+y+z))

subject to

{x,y,z}==rotated_lorentz(1);

cvx_end

I want to know the number of n(n is 1 or 3?) in the example and I also want to know the meaning of ‘n’.

Thank you.
