y=max(x);
row=0;
for i=1:length(x)
if x(i)==y
row=i;

Probably this line
x=sum(a==0);
should really be this
x=sum(any(a),2);
The whole thing looks like it could be done in 1 line
[~,row]=max( sum(any(a),2) );

I don't know what should be the result r, but I can see that the value of r is erased each loop
r=rows
maybe you can initialize r
r=[]
then write
r(end+1)=rows
