# Matrix Math Resources

Hi all,

I find dealing with matrices in Maya very powerful but sometimes not exactly intuitive so I thought I'd start a thread to share resources that will help you make matrix constraints, calculate vectors etc.

Feel free to post links about linear algebra that you found useful.

Kimon Matara has some great basic tutorials on how matrices are handled in Maya, how to get vectors and what to do with them. Check out his other tutorials as well! http://www.kimonmatara.com/hands_on_matrices/ http://www.kimonmatara.com/intro_to_vectors/

Of course Vasil posted a bunch of great matrix math tutorials http://bindpose.com/maya-matrix-nodes-blending-matrices/ http://bindpose.com/maya-matrix-nodes-part-2-node-based-matrix-twist-calculator/

This class by Autodesk does a great job of introducing you to 3D maths. https://area.autodesk.com/learning/class3_q1_2012/

And of course Marco Giordano's classic "Building a pose reader with Maya nodes" https://vimeo.com/64958089

Got any great links? Please do share them!

I just stumbled on this playlist on youtube which provides really nice explanations for linear algebra concepts.

Here a some more math links:

Wow, that's a solid list! Thanks a lot for these! I have seen some of them, but I will definitely do my best to digest all of it!

Here's another link to add to the list. He goes over vector maths and applies it to how to calculate placement for pole vectors. https://vimeo.com/240328348

These are really cool links! I didn't know about the Kimon Matara ones and they are so nicely written!
