WebThere are two ways to substitute a matrix into a polynomial: element by element and according to matrix multiplication rules. Element-by-Element Substitution. To substitute a matrix at each element, use the subs command: syms x f = x^3 - 15*x^2 - 24*x + 350; A = [1 2 3; 4 5 6]; subs (f,A) ans = [ 312, 250, 170] [ 78, -20, -118] Webnumden Extract numerator and denominator collapse all in page Syntax [N,D] = numden (A) Description example [N,D] = numden (A) converts A to a rational form where the numerator and denominator are relatively prime polynomials with integer coefficients. The function returns the numerator and denominator of the rational form of an expression. howling moving castle piano
