%ss is array double
%profit is array double
g=zeros(height(ss));
maxCat=3;
for i=1:height(ss)
z=find(ss(:,i)>0);
if ~isempty(z)
[val,idx]=sort(profit(z),'descend');
ret=idx(1:maxCat);
g(ret,i)=1;
end
end
thank you

I'm ignoring the comments Walter gave you to make it more clear what edits I mean:
%ss is array double
%profit is array double
g = zeros(height(ss));
maxCat = 3;
for i=1:height(ss)
z = ss(:,i)>0;
if ~any(z)
[val,idx] = sort(profit(z),'descend');
ret = idx(1:maxCat);
g(ret,i) = 1;
end
end
This will have the same effect as the code you posted.
