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.

This example shows how to represent a polynomial as a vector in MATLAB® and evaluate the polynomial at points of interest.
Calculate polynomial roots numerically, graphically, or symbolically.
This example shows how to use the
polyder functions to analytically integrate or differentiate any polynomial represented by a vector of coefficients.
This example shows how to fit a polynomial curve to a set of data points using the
There are many functions in MATLAB that are useful for data fitting.
