- Hi,
-
- I was just wondering if somebody could help out regarding matrix differentiationThe problem is to minimize:
-
- y= x'Ax + 2x1 + 3x2 - 10
-
- where A is a 2x2 matrix : 25 7
- 7 13
-
-
- and x is the (x1 x2) column vector and x' denotes the transpose.
-
- It's easy if one expands the x'Ax term but I was wondering if there was some way doing it using matrix differentiation.
-
- Thanks for any help in this regard.
