Is any particular notation given below preferred in mathematical writing? Why?
Given a set of vectors →x1,→x2,…,→xNx⃗ 1,x⃗ 2,…,x⃗ N, we can write an individual vector →xi as follows.
→xi=(x(1)i,x(2)i…,x(n)i)T→xi=(x(i)1,x(i)2…,x(i)3)T→xi=(xi,1,xi,2…,xi,n)T→xi=(x1,i,x2,i…,xn,i)T
Is any method considered better than the other or is it completely up to the author?
