Which epoch is the training result of the train function

I see a strange (training) performance degradation at the moment in a neural network structure that I am using. Quick question:
What epoch does the trained network that the train function returns belong to? Always the best epoch? or the very last one? Because currently I see the best epoch somewhere in the middle of my training and then the performance decreases significantly. If the very last epoch was output, then I know why my performance is decreasing.

The train function returns the last epoch by default. This behaviour can be modified by using the ValidationPatience argument under training option. There are some examples demonstrating the use of the of training option which can be accessed here.

For a shallow neural network you can use the code:
net.trainParam.max_fail = x
where x is the number of fails in increase the performance.
This is the validation fail parameter. The default value is 6.
