How can i rearrange a vector ?

I need you help in matlab

if A=[8 1 12 3 6 10 13 3];

          AVG=sum(A)/length(A);

          i need to neglect all values that below the AVG

        so i get   B=[8 12 10 13]

can you help me to perform this task in general

B = A(A>=mean(A))

if i have number of nodes (8) each node has its ID as follow ID=[ 1 2 3 4 5 6 7 8]

each node has its related Power using structure array ID.power=A

A=[8 1 12 3 6 10 13 3]

you help me to rearrange the matrix A depending on the mean

what about rearranging the ID vector ?

thanks in advance

result ID=[1 3 6 7]
