Improve the endless loop

 [st,message] = system(cmd);
 while st~=false
 [st,message] = system(cmd);
 end

In the case where st is always false , I stuck in a loop for ever which is't good ! how could I improve that by adding a threshold a break ?

any suggesion ?

Thanks,

t=rem(now,1);
[st,message] = system(cmd);
while st~=false
[st,message] = system(cmd);
if  rem(now,1)-t > 0.0001
   break
end
end

Since the condition is not that important to you that you consider break after a while, you can also try this,

[st,message] = system(cmd);
if st~=false
   pause(2);
end
[st,message] = system(cmd);

count = 1;
while st~=false && count < 1000
 [st,message] = system(cmd);
 count = count + 1;
end
