Bertini.BMSolve

Solves zero dimensional non-homogeneous polynomial system using mult-homogenization with default configurations.

Syntax

Bertini.BMSolve(M:LIST)

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 M: List of polynomials in the system.

Example

-- We want to solve the non-homogenous system x[1]^2+x[2]^2-5=0, x[1]x[2]-2=0, using multi-homogenization. 

Use S ::= QQ[x[1..2]];             --  Define appropriate ring 
M := [x[1]^2+x[2]^2-5, x[1]x[2]-2];

-- Then we compute the solution with
Bertini.BMSolve(M);

-- And we achieve a list of lists containing finite solutions:
