hi
in mathematica
how i can produce a general n by n matrix so that each of its elements be a variable of t???
how i can take derivative of this matrix with respect to variable t?
how i can with equating this n by n matrix with another n by n matrix which its elements are known obtain unknown elements of this general n by n matrix?
