Hi ,
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.
