places of code snippets

Hi,

I'm feeling lazy; What are some good sites to search for code snippets. E.g. code to just multiply 2 4x4 matrices stored linearly in memory?

I wrote like matrix code many times of all sorts; Now I have to write it again :S.

I feel the first reply will be like "Quit being lazy and write matrix multiplication again" lol.

I wasted one hour looking for multiplying 4x4 matrices of code where I could have done it myself in 5min lol. Maybe my brain is getting fried or something.

Thanks :)

I'll give you a hint. For as many people reading this, as well.

Half will know how to do what you want, and the other half will WANT to know what you want to do. Your problem:

Code:

---

I wrote like matrix code many times of all sorts;

You need it again.

You didn't specify what language you wanted it in, nor what you used before.

If you write out the mathematical steps involved, along with some sample data & expected results, I'd bet that someone helps you code it
