Polynomial Root Finder
|
|
Description
|
This program finds all roots, real, complex, and repeated, of an nth degree polynomial equation. The program uses the cZeros() function repeatedly, and in many cases returns results in exact form rather than decimal form. Polyroot() is my alternative to the TI Polynomial Root Finder, which sometimes introduces small imaginary parts to real roots and vice versa, especially for repeated roots. In general, it is slower than the TI program, but the form of the results is usually more convenient. If you want to graph the function also, see Polygraf().
