PolynomSolver< T > Class Template Reference Math Library
#include <polynomsolver.h>
Each function uses the followig format: a*x^(n) + b*x^(n-1) + ... = 0 Return value is the number of real solutions. All results are stored in x. This array must have at least n elements. If the imaginary part of a complex number is between -epsilon and epsilon the number is treated as a real number.
