What is Mu and Performance Gradient ?

I see these parameters in the NN Toolbox but I can't seem to find an explanation on what they are and how they work.

Anyone here can please clarify it for me or point me in the right direction please?

Thank you in advance!

Thank you! I think I see it, "Marquardt adjustment parameter" as is called in doc trainbr and more or less explained in doc trainlm.
