在 MATLAB Online 中打开

nones = 10;
nv = 50;
V = zeros(1,nv);
V(randperm(nv,nones)) = 1;

I'm sorry. I cannot/will not keep on chasing totally new questions in the comments. That turns one question into an extended personal consulting session. If you have another question, then ask it. AS ANOTHER QUESTION.
