numpy.poly() in Python
The numpy.poly() function in the Sequence of roots of the polynomial returns the coefficient of the polynomial.
Seq : sequence of roots of the polynomial roots, or a matrix of roots.
Return: 1D array having coefficients of the polynomial from the highest degree to the lowest one.
c * x**(N) + c * x**(N-1) + … + c[N-1] * x + c[N] where c always equals 1.
Coefficients of the polynomial: [ 1. -3. 2. 0.] Above polynomial = 3 2 1 x - 3 x + 2 x
Coefficients of the polynomial: [ 1. -11. 46. -92. 88. -32. 0.] Above polynomial = 6 5 4 3 2 1 x - 11 x + 46 x - 92 x + 88 x - 32 x
