MATLAB: Function to find relations

relations

hi,

I have some clusters of users, I need to find intersections among the clusters. i.e is x=no. of users y=no. of users

what I need is x ∩ y=z

z is the no. of users in both clusters x and y

can I find a function do that?

many thanks in advance

Did you look at functions like intersect() and ismember()?

x = X(~ismember(Y,p));

[~,ii] = setdiff(Y,p);
x = X(ii);

Try

function main
x0=1;
sol=fzero(@f,x0);
function y=f(x)
z=[-300.00 1082.00 7494.20];
B=[1.637510856e-06  -2.252209129e-05 0.0001949906158 9.284333582e-06

   0.0001949906158  0.03330113194    0.5146272212    0.03759452473

for k=1:length(x)
  xk=x(k);
  a=[1 z(3)*xk/10000 z(2)*xk/10000 z(1)*xk/10000]';
  y(k)=a'*B*a-1;
end

Best wishes
