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

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!

David
