Polynomials are equations of a single variable with nonnegative integer exponents. MATLAB® represents polynomials with numeric vectors containing the polynomial coefficients ordered by descending power. For example,
[1 -4 4] corresponds to x2 - 4x + 4. For more information, see Create and Evaluate Polynomials.

- Create and Evaluate Polynomials
This example shows how to represent a polynomial as a vector in MATLAB® and evaluate the polynomial at points of interest.
- Roots of Polynomials
Calculate polynomial roots numerically, graphically, or symbolically.
- Integrate and Differentiate Polynomials
This example shows how to use the
polyderfunctions to analytically integrate or differentiate any polynomial represented by a vector of coefficients.
- Polynomial Curve Fitting
This example shows how to fit a polynomial curve to a set of data points using the
- Programmatic Fitting
There are many functions in MATLAB that are useful for data fitting.
