Hi ,(adsbygoogle = window.adsbygoogle || []).push({});

I am stuck with the problem of finding derivative wrt. A of following function:

Def:

y - column vector of size mx1

A - matrix of size m x n

b - column vector of size n x 1

K - matrix of size n x n

y' - denotes the transpose

K^-1 - denotes inverse

f(A) = (y - Ab)' (AKA')^-1 (y-Ab)

Can anyone please help me?

thanks,

abhishek.
