Where to load a previous saved neural network

Hello.

I have this code

rede = patternnet;
net = train(rede, input, target); 
exemple1 = net;
save exemple1;

where i train a network and save it because I want to have the same output the next time I run the code. Where exactly do I put load exemple1 ? Do I have to comment the rede = patternnet and net =train or should I leave it?
