Coefmatrix

Function: coefmatrix ([<eqn_1>, ..., <eqn_m>], [<x_1>, ..., <x_n>]) Returns the coefficient matrix for the variables <x_1>, ..., <x_n> of the system of linear equations <eqn_1>, ..., <eqn_m>.

          (%i1) coefmatrix([2*x-(a-1)*y+5*b = 0, b*y+a*x = 3], [x,y]);
                                           [ 2  1 - a ]
          (%o1)                            [          ]
                                           [ a    b   ]
