Abou using multiple <= in one Constraints

[cheng Zhou]

Dear Dr Johan Löfberg

sdpvar x y z p

Constraints=[Constraints,0<=x<=y<=z<=p<=1];

And the another Constraint is

Constraints=[Constraints,0<=x];

Constraints=[Constraints,x<=z];

Constraints=[Constraints,z<=p];

Constraints=[Constraints,p<=1];

Which one is better? the first and the second?

I am wondering whether you can help with this issue?

Thank you!
