I have to define a state space equation. there is a vector with 5 members as stats such that all states(members of the vector) are real numbers.
which notation is true for this case?
x=[x1,x2,x3,x4,x5] ∈ R
x=[x1,x2,x3,x4,x5] ∈ R^5
where ^ implies that the number 5 is the power of R
is both are correct. which one can I use to introduce my states?
