Particle Swarm Optimization in a 2d searcher space

Hey.
I have another question to the particle swarm optimization. Attached you can see my script for the PSO and the function (Rosenbrock function).
I defined my Boundaries and number of dimensions:
VarMin = -5 VarMax = 5 nVar = 2 Then of course I get for the GlobalBest a vector with 2 columns. For example:
Position: [0.9261 0.8588] And the Cost: 0.0056
The Rosenbrock function has it's minumum at the origin. Why I don't get for my 2d searcher space the position [0 0] and the cost value also around zero? I hope you can help me with my understanding problem.
Kind regards

The Rosenbrock function has its minimum at the point [1,1], not the origin.
