int solvepoly(float coef[], float &roots[], int maxiter=0)
coef
An array of coefficients of the polynomial.
You must order the coefficients such that coef[i]
should be x^i
.
This is reverse of the order you would write the polynomial out normally.
&roots
The function overwrites this array with the real roots of the polynomial, in ascending order.
Returns
The number of real roots.
