15.7.1  Matrix of a system

The syst2mat command turns a system of linear equations into its augmented matrix. (For this command, the augmented matrix of Ax=b has the column vector −b glued to the right of A.)

• syst2mat takes two as arguments:
  • eqns, a list of the equations or expressions (assumed to be equal to zero) of a linear system.
  • vars, a list of the variable names.
• syst2mat(eqns,vars) returns the augmented matrix of the system.

Remark.

Note that the variables must be purged before syst2mat is called.
