Setting an operator as a function or variable?

What I would ideally like is to have a variable or function set to a derivative operator, so Variable1*variable2 = derivative of variable2 with respect to some constant.

 

I would like this as I am dealing with equations of numerous constants and some derivatives go to 0. "Do this operator on every operand possible in this following equation" just makes it easier than figuring out which ones I need to do by hand.

What you're asking for I don't think can be done; certainly not in Prime.

 

There is a gradient operator in Mathcad 15:

but you can "roll your won:

    Yeah I didn't think it would be implemented... Very disappointing software...

     

    I gave your idea a shot and it will work. Dot-product on that vector with a [1,1,1] vector gives me back what I want. Thank you for helping me. 🙂
