Finding the partial derivatives of a vector containing polynomials

I have a vector that is 4x1size and contains 4 polynomials with 4 variables each (w,x,y,z). I want to find the partial derivatives wrt each polynomial and then store it as a matrix (4x4 matrix).

So what I have is molflow = [ fA; fB; fC; fD ] (4x1 vector). Want to find partial derivatives wrt w,x,y,z for fA, fB, fC, fD and store it as a 4x4 matrix. My idea is to multiply 'molflow' with 'partial derivative vector' size 1x4 in order to obtain 4x4 matrix.

This is done easily mathematically. Is this possible on matlab? Are there any alternative solutions?
