MATLAB: Operator matrix for matrix differentiation derivativedifferentiateoperator matrix Is there a way to define an operator matrix, such that: Best Answer symbolicfunction dNdv = diffmtx(v,N) % v -vector m x 1 - sym array % N - matrix m x n - sym array rz = arrayfun(@(ii)diff(N(ii,:),v(ii)),(1:numel(v)).','un',0); dNdv = cat(1,rz{:});end Related SolutionsMATLAB: Factoring a symbolic matrix The expression appears in the denominator of all the elements of the matrix, so just multiply it: syms s w1 L Eq = [s/((s^2 + w1^2)*L), w1/((s^2 + w1^2)*L); (-w1)/((s^2 + w1^2)*L), s/((s^2 + w1^2)*L)];Eqf = Eq * (s^2 + w1^2)*Lproducing: Eqf =[ s, w1][ -w1, s]Another option is: [n,d] = numden(Eq)producing: n =[ s, w1][ -w1, s]d =[ L*(s^2 + w1^2), L*(s^2 + w1^2)][ L*(s^2 + w1^2), L*(s^2 + w1^2)].
