Minor improvement in Gaussian Elimination in Julia

[mika314]

• Remove extraneous assignment

[leios]

I'm 50:50 on this one. It makes it ~2% harder to read (simply because you have to think about why it works for the first element at all without throwing an error in the internal for loop) and adds another unnecessary assignment for sum. Ultimately not a big deal either way.

Obviously, I don't mind changing things if you guys think it's better though!

As another note: would you mind updating the corresponding .md file with the change in line-numbers if we do merge it?

[mika314]

@leios thank you for pointing to .md file. I'll do it.

It's not the world most divisive question, but I think I'm with @leios in this case. Our goal is to explain algorithms, That first line is super explicit and matches the text.
Obviously in my own code it's way more obfuscated haha ^^

[mika314]

I am fine if you reject the PR, especially if the PR makes the code inconsistent with the text in the book.

[jiegillet]

Not inconsistent, your modification is fine, just, as leios said, 2% less readable for the purpose of writing a book.

I thought about it a bit. It's probably better with the change here.
