Question: Gradient of a vector not gradient of a scalar function

I replied to the following thread but after further thought I probably start a new thread:

http://www.mapleprimes.com/forum/multivariate-directional-derivative-0

Is the DirectionalDiff command the tool I should use to find the gradient of a vector.  MAPLE HELP has a gradient as well as NABLA command but it seems they can only be used on scalar functions to convert them into a gradient vector.  Instead of this I am seeking the gradient of a vector which then yields a 2nd order tensor.  Is there something else I should use?

Please Wait...
