### 2.52.1 Matrix of a system : `syst2mat`

`syst2mat` takes two vector as argument. The components of the first vector are the equations of a linear system and the components of the second vector are the variable names.
`syst2mat` returns the augmented matrix of the system AX=B, obtained by gluing the column vector −B to the right of the matrix A.
Input :

`syst2mat([x+y,x-y-2],[x,y])`

Output :

`[[1,1,0],[1,-1,-2]]`

Input :

`syst2mat([x+y=0,x-y=2],[x,y])`

Output :

`[[1,1,0],[1,-1,-2]]`

Warning !!!
The variables (here `x` and `y`) must be purged.
