Hi Abdulaziz,

The "perform" function returns the performance of the trained network calculated according to the net.performFcn and net.performParam property values.

The output argument "tr" is a structure which contains information in fields such as:

• Training, data division, and performance functions and parameters
• Data division indices for training, validation and test sets
• Data division masks for training validation and test sets
• Number of epochs (num_epochs) and the best epoch (best_epoch).

Please refer to their respective documentation for more information : train shallow neural networks, perform. I hope this helps!

yeah but it also has performance as well. but is different than the performance i get from using the function perform
