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