BSolve

Solves zero dimensional Homogenous or Non-Homogenous polynomial system with Default Configurations.

Syntax

Bertini.BSolve(M: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.

M: List of polynomials in the system to be solved.

SysTyp: Type of the system to be solved. Homogeneous ("hom") or nonhomogeneous ("Nhom").

Zero Dimensional Non-Homogenous Solving

Example

-- We want to solve zero dimensional non-homogenous system x^2+y^2-5=0, xy-2=0. 

Use S ::= QQ[x,y];             --  Define appropriate ring 
M := [x^2+y^2-5, xy-2];
SysTyp := "Nhom";

-- Then we compute the solution with
$Bertini.BSolve(M,SysTyp);

-- And we achieve:
