The roots of the polynomial are calculated by computing the eigenvalues of the companion matrix, A. A = diag(ones(n-1,1),-1); A(1,:) = -p(2:n+1)./p(1); r = eig(A) The results produced are the exact eigenvalues of a matrix within roundoff error of the companion matrix, A .

The roots of the polynomial are calculated by computing the eigenvalues of the companion matrix, A. A = diag(ones(n-1,1),-1); A(1,:) = -p(2:n+1)./p(1); r = eig(A) The results produced are the exact eigenvalues of a matrix within roundoff error of the companion matrix, A .

설명. r = roots (p) 는 p 로 표시되는 다항식의 근을 열 벡터로 반환합니다. p 는 x n 의 계수로 시작하여 n+1 개의 다항식 계수를 포함하는 벡터입니다. 방정식에 존재하지 않는 중간 차수의 항은 계수를 0 으로 표시합니다. p = [3 2 -2] 는 다항식 3 x 2 + 2 x − 2 를 나타냅니다. roots 함수는 p 1 x n + ... + p n x + p n + 1 = 0 형식의 다항 방정식을 풉니다. 다항 방정식은 음이 아닌 지수를 갖는 ...

root (p,x) returns a column vector of numbered roots of symbolic polynomial p with respect to x. Symbolically solving a high-degree polynomial for its roots can be complex or mathematically impossible. In this case, the Symbolic Math Toolbox™ uses the root function to represent the roots of the polynomial. example.

The roots of the polynomial are calculated by computing the eigenvalues of the companion matrix, A. A = diag(ones(n-1,1),-1); A(1,:) = -p(2:n+1)./p(1); r = eig(A) The results produced are the exact eigenvalues of a matrix within roundoff error of the companion matrix, A .

The roots function calculates the roots of a single-variable polynomial represented by a vector of coefficients. For example, create a vector to represent the polynomial x 2 − x − 6 , then calculate the roots. p = [1 -1 -6]; r = roots (p) r = 3 -2. By convention, MATLAB ® returns the roots in a column vector.
