Polynomial function in matlab
WebThe polynomial coefficients in p can be calculated for different purposes by functions like polyint, polyder, and polyfit, but you can specify any vector for the coefficients. To evaluate a polynomial in a matrix sense, use polyvalm instead. WebThis MATLAB function, where r is a vector, returns the coefficients of the polynomial whose roots are the elements of r.
