5.61.1  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.
