Matrix of a system : syst2mat

### 4.53.1 Matrix of a system : syst2mat

syst2mat takes two vectors as arguments. 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.
