## Bertini.BCMSolve

Solves zero dimensional non-homogeneous polynomial system using multi-homogenization with User Configurations.

### Syntax

```Bertini.BCMSolve(M:LIST, 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.

#### Example

```-- We want to solve the system x^2+y^2-5=0,xy-2=0, using multi-homogenization, for adaptive precision.

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

-- Then we compute the solution with
\$Bertini.BCMSolve(M,ConfigSet);

-- And we achieve:
