I would like to do something like a derivative with respect to a vector or really anything involving a vector (of known dimension, but unknown values) going in and a vector coming out:
x= 4 by 1 vector
A = 4 by 4 matrix
diff( Transpose(x) * A * x, x)
should return (1/2)*A*x
Is there software that can do this? I am familiar with maple and matlab, but I don't think either of them can do this.
Any suggestions?
Thanks!
