## Bertini.BZCSolve

Solves zero dimensional Homogeneous or Non-Homogeneous polynomial system with User Configurations.

### Syntax

```Bertini.BZCSolve(M:LIST, SysTyp:STRING ,  ConfigSet: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.

• @param SysTyp: Type of polynomials in the system. Homogeneous (hom) or nonhomogeneous (Nhom).

• @param ConfigSet: List of strings representing Configurations to be used by bertini. For detials about configuraion settings see Bertini mannul http://www.nd.edu/~sommese/bertini/BertiniUsersManual.pdf.

#### Example

```-- Zero dimensional Non-homogenous solving with fixed higher precision
-- We want to solve zero dimensional non-homogenous system x^2+y^2-5=0, xy-2=0, for fixed higher precision.

Use S ::= QQ[x,y];             --  Define appropriate ring
M := [x^2+y^2-5,xy-2];
SysTyp := <quotes>Nhom</quotes>;
ConfigSet := [<quotes>MPTYPE: 1</quotes>, <quotes>PRECISION: 128</quotes>];

-- Then we compute the solution with
Bertini.BZCSolve(M,SysTyp,ConfigSet);

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