Polynomial coefficients, specified as a vector. For example, the vector [1 0 1] represents the polynomial x 2 + 1, and the vector [3.13 -2.21 5.99] represents the polynomial 3.13 x 2 − 2.21 x + 5.99. For more information, see Create and Evaluate Polynomials. Data Types: single | double Complex Number Support: Yes

This example shows how to represent a polynomial as a vector in MATLAB® and evaluate the polynomial at points of interest. Representing Polynomials MATLAB® represents polynomials as row vectors containing coefficients ordered by descending powers. For example, the three-element vector p = [p2 p1 p0]; represents the polynomial

Description. C = coeffs (p) returns coefficients of the polynomial p with respect to all variables determined in p by symvar. C = coeffs (p,var) returns coefficients of the polynomial p with respect to the variable var. [C,T] = coeffs ( ___) returns the coefficient C and the corresponding terms T of the polynomial p.

Coefficients of polynomial, returned as a symbolic number, variable, expression, vector, matrix, or multidimensional array. If there is only one coefficient and one corresponding term, then C is returned as a scalar.

Create a polynomial expression from a numeric vector of floating-point coefficients. The toolbox converts floating-point coefficients to rational numbers before creating a polynomial expression. p = poly2sym ( [0.75, -0.5, 0.25]) p = (3*x^2)/4 - x/2 + 1/4 Specify Polynomial Variable

Polynomial coefficients, returned as a numeric row vector. Tips To extract symbolic coefficients of a polynomial, use coeffs . This function returns a symbolic vector of coefficients and omits all zeros. For example, syms a b x; c = coeffs (a*x^3 - 5*b,x) returns c = [ -5*b, a]. Introduced before R2006a How useful was this information?

MATLAB® represents polynomials as row vectors containing coefficients ordered by descending powers. For example, the three-element vector. p = [p2 p1 p0]; represents the polynomial. p ( x) = p 2 x 2 + p 1 x + p 0. Create a vector to represent the quadratic polynomial p ( x) = x 2 - 4 x + 4. p = [1 -4 4]; Intermediate terms of the polynomial that have a coefficient of 0 must also be entered into the vector, since the 0 acts as a placeholder for that particular power of x.

Create a polynomial expression from a symbolic vector of rational coefficients. p = poly2sym (sym ( [1/2, -1/3, 1/4])) p = x^2/2 - x/3 + 1/4. Create a polynomial expression from a numeric vector of floating-point coefficients. The toolbox converts floating-point coefficients to rational numbers before creating a polynomial expression.
