G'day, Namir:

Just a question:

As you say X() represents the guesses for the roots, which might be complex, then we must assume X() is a complex array, right ?

Also, you say the array a() represents the coefficients. Are they assumed to be complex in the general case or are you considering just polynomials with real coefficients ?

Finally, pretty please, correct that "Foummulas" (sic) in the thread title, it's a real eyesore. XD

Regards.

Yes both arrays X() and a() can be complex and the mathematical operations work with complex numbers. For programming languages like Matlab, the operations and functions automatically handle real and complex numbers. For other languages (not sure about Python) one may have to use complex operators and functions just to be sure that the math expressions can handle real and complex numbers.
