Bertini.BSolve
Solves a zero dimensional homogeneous or non-homogeneous polynomial system of equations with default configurations.
Syntax
Bertini.BSolve(P:LIST, SysTyp:STRING)
Description
Please note: The function(s) explained on this page is/are using the ApCoCoAServer. You will have to start the ApCoCoAServer in order to use it/them.
@param P: List of polynomials of the given system.
@param SysTyp: Type of polynomials in the list P. Homogeneous ("hom") or nonhomogeneous ("Nhom").
@return A list of lists containing the finite (or real) solutions of the system P.
