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
