Sort vector and obtain Boolean output based on the vector index

Hello,

I am designing a voltage balancing algorithm for converter application. It can be easily done by using a code-based MATLAB function block, but it requires some compiling time whenever I initilize the model. It would be interesting to me to build the function using blocks from simulink. I know there is a sort block from DSP System Toolbox, but now I am stuck on given values to the output signal based on vector index and n. Would be appreciated if you can provide me a example to implement this function using blocks.

v=rand(10,1);
n=5;
g=zeros(10,1);

[val,ind]=sort(v);%ascending
for i=1:n
    g(ind(i))=1;
end
