How to avoid an Infinite Loop?

Hi,
I'm encountering an infinite loop problem. I tried to debug my code but couldn't figure it out, so I would appreciate your thoughts and ideas.
[nComponents,sizes,members] = networkComponents(NetA);
[nComponentsB,sizesB,membersB] = networkComponents(NetB);
while sizes(1)~=sizesB(1)
for ii=1:Nodes
if nnz(NetA(ii,:))<1 && nnz(NetA(:,ii))<1 && ~ismember(ii,attack)
C(ii,:)=0; % All nodes in Layer B coupled to neighboring nodes will get failed
indab=ismember(inda,ii);
indab=find(indab);
NetB(indb(indab),:)=0;
NetB(:,indb(indab))=0;
end
end
% Propagation back to Layer A
for pp=1:Nodes
if nnz(NetB(pp,:))<1 && nnz(NetB(:,pp))<1
C(:,pp)=0;
indba=ismember(indb,pp);
indba=find(indba);
NetA(inda(indba),:)=0;
NetA(:,inda(indba))=0;
end
end
end
Where,
"NetA" and "NetB" are square symmetric matrices.
"inda" and "indb" are row vectors of the same size.
"attack" and "Nodes" are positive integers.
"sizes(1)" and "sizesB(1)" are positive integers.

You increases your chances to get a prompt answer if you provide sample data so that we easier can run your code.

Waseem,
Nothing in the entire while loop alters either 'sizes' or 'sizesB'. So if sizes(1) ~= sizesB(1), that condition will not ever change, leading to an infinite while loop. For the loop to terminate, you will have to change either sizes(1) or sizesB(1) within the loop, in such a way that the two eventually are equal.
