If only I'd found this earlier, I might still have hair
Check out this awesome site that calculates derivatives of linear algebraic equations:
This is normally so tedious, not anymore though.
I just found this really super useful website, in case you ever struggled to find the derivative of a vector or a matrix:
This will save me a bunch of time next time I will need to take the derivative of a log likelihood :)
This is splendid. Fun as it is to read huge books on matrix calculus, even more fun to have the machine do it.
Do you need to differentiate a complicated function, possibly including matrices and vectors? Try the MatrixCalculus online
This is cool: MatrixCalculus provides matrix calculus for everyone. It is an online tool that computes vector and matrix derivatives (matrix calculus). Export to python or LaTeX
