Hi all, I need to differentiate a 4x4 matrix M with respect to four variables x1,x2,x3 and x4. I have tried to use the function D as follows: D[M,{{x1,x2,x3,x4}}] what I get is a 4x4 matrix and each term in this matrix is a vector. Am I right when I used this function or there is another function to do so? Thanks
