About CVX summation problem

The Problem as follow, I think it is a convex optimization problem, Is it really a convex? minimize ∑i=1 to M (Pi)^2, for example if M=3, (P1)^2+(P2)^2+(P3)^3, Pi is the variable which I want to optimize 3 Constraint: ∑i=1 to M Pi=1 ∑i=1 to M PiaEi<=b , where a,b are constant, Ei are also array of constant 0<=Pi<=1, i=1,…M My CVX coding as following: a=0.0005; b=5; e={1,3,6,9,12}; x={0,0,0,0,0}; cvx_begin obj=0; sub=0; sub1=0; variable p(5,1) for i=1:5 obj…

is it correct to do like that?
variable p(5,1)
for i=1:5
obj=obj+p(i)*p(i)
end
minimize (obj)
