Understanding Legendre-fenchel Transform, looking for an easy example and intuition Looking for help in understanding this transform. I have no background in real analysis but need this stuff for my research.
I hope someone can give me some light on the intuition behind this transform and better if you can provide some example I can work with. 
Thanks in advance.
I already found some information related to it here
But, still not able to fully understand.
Thanks.

Will answer my own question since I found a very good reading material which helped me to fully understand the topic.
If interested, take a look here.
