I very much like the form of this, yet I wish that the dependencies were ordered differently, such that one would not need to jump around (e.g. eigenvalues before determinants, since the latter are defined by the former).
Worth checking the Wikipedia page on matrix calculus to see which version of the notation you use! This is in numerator (iirc) and so d (vec x) / d(t) = (vec x). I was used to d (vec x) / d(t) = transpose(vec x), and so this cookbook confused me for ages :S
When I learned about matrices in school it really bored me, even though math in general really captures my interest. Can anyone recommend a good source that makes matrices interesting and captivating?
TL; DR:<p>What is this? These pages are a collection of facts (identities, approximations, inequalities, relations, ...) about matrices and matters relating to them. It is collected in this form for the convenience of anyone who wants a quick desktop reference.<p>In case you were, uh, expecting to see Keanu Reeves in a kitchen apron.
Dang it! I thought this was gonna be a cookbook from the movie Matrix. Like how to bake the cookies the oracle made, or the steak Cypher ate. That looked good.
