Suggestions

Hi Sun,

Nice work! Your page is informative and has nice examples. I have a few suggestions:

1. Highlight some key words for long paragraph then it is more easier to get the point as well as to read.
2. Some pictures in the page should be larger.
3. Add some explanation for pseudo code.
4. Put the formula to the centre of the line will make the page more beautiful.

Bests,

YuYan

Dear Yuanyu

Thank you very much for your great support and kind explanation. It really helps me a lot. Regarding for suggestions 1, 2 and 4. I have already modified that and changed accordingly. As for your suggestion 3, I previously thought about that but I didn't add that because I want to maintain the code brevity and the detail explanation of the code has already been explained in the previous theory part. Thank you.

Regards Arthur
