Let our input polynomial be x^3 – 3x^2 – 4x + 12Īs we can see in the output, the roots of the polynomial x^3 -3x^2 -4x 12 are -2, 3, 2 Recommended Articles.In this example, we will take a polynomial of degree 3 with real roots. We will follow the following steps:Īs we can see in the output, we have obtained complex roots for the input polynomial x^2 + 1, as expected by us. In this example, we will take a polynomial of degree 2 and with complex roots. Let our input polynomial be x^5+2x^2 + x-2Īs we can see in the output, we have obtained complex roots for the input polynomial x^5 +2x^2 + x -2, as expected by us.In this example, we will take a polynomial of degree 5. Find rows in matrix where entries match certain constraints In Matlab, i have a matrix (MxN) and I want to find the rows whose entry in a specific column is equal to a specified value. Let us now take some examples where polynomials have non-real roots.
