optimizing vector variables with N vector

Hello all,

I am writting a code for optimization where I have two optimizing vector variables with N vector like a(1,N) and b(1,N).How I can declare these variables within a function for objective function?

I am trying like that, but it's not getting the ans.

N=10;

function r= mainfcn(z,N)

a=z(1,N);

b=z(N+1,2*N);

r = a.^2 + b.^2 - 1;

end

Thanks in advance.

hello

I suspect this is the intention (corrected code) :

N=10;
z = rand(1,2*N); % dummy data (length must be >= 2N

r= mainfcn(z,N)

 function r= mainfcn(z,N)
    a=z(1:N); % here (1:N) and not (1,N)
    b=z(N+1:2*N); % same fix
    r = a.^2 + b.^2 - 1;
 end

Thanks. Now the code is showing perfect result.
