Hey guys,
Iv been given the function:
V(x,y) = kx^2 + k[(y-x)^2] + ky^2
They say :
Write down a symetric matrix A such that V = (X^T)AX where X = (x,y)^T
T: Transpose of matrix.
Whaaaat the helll???
Thanks.
Thanks man, i did something like that but it didnt come out like that. You just need to take the co-effients of the equation and match it with the equation determined by the multiplication....by the way, how did you know they were looking for a 2x2?
a = 2k
b+c = -2k => b=c=-k
d = 2k
