FNCFunctions vs FundamentalsNumericalComputation: which Julia package to install

[manan-gup]

Hi, I came across this book (https://fncbook.com) recently and was trying to follow the Julia track. The "Julia setup" section of the appendix and the introduction suggest different packages for Julia (locations referenced below). Can someone clarify what needs to be done?

Now you enter `add FNCFunctions` and press `Enter`. This will install the functions that are used in this book. It may take a few minutes to download and install everything. This is a one-time operation.

P.S. From looking at the respective repositories, it seems to me that FNCFucntions is the one that goes with this version of the book. I'll move forward with that one and see where that gets me.

That's my bad. You should use FNCFunctions with the latest online version of the book. But you will also need to one-time install other packages to run some of the examples (anything imported by using).

The FundamentalsNumericalComputation is older and tries to load all those packages in one shot every time, which slows things down a lot.

There is infrastructure in recent Julia versions to make all this less painful, but I have not attempted to use that yet.

Thanks for the clarification, and also for writing the book!
