Using mat lab to solve order crossover problem

These are my two parents I am using to produce offspring. In doing so I need to use the order crossover method. Here is some code I have and I am confused on how to randomly generate a crossover point, that will then use the ORDER crossover method to produce results. Here is some code I have after taking smaples from different sources. Am I on the right path?

P1=[1,9,12,2, 7,5,8,11,6,13,14,10,3,4,16,15];

P2=[16,13,14,2, 12,7,3,4,1,10,5,6,9,8,15,11];

[m,n]=size(1,7); %C1=P1; %C2=P2;

For i=5:11

if i<5 && i>11

n(i) *maybe use the compare function?

end

%Crossover point cp=randperm(1);

b1 = [P1(1, 1:cp), P1(2, cp+1:end)]; b2 = [P2(1, 1:cp), P2(2, cp+1:end)];
