Obtaining the coefficient matrix of multivariable homogeneous linear equation system. |
Hi here, I've a multivariable homogeneous linear equation system as shown below: $ gp ? trmat=[x1,x2;x3,x4];A=[a,b;c,d]; ? A * trmat - trmat *A %50 = [ x3*b - x2*c x2*a + ((-x1 + x4)*b - x2*d)] [-x3*a + ((x1 - x4)*c + x3*d) -x3*b + x2*c] Where, trmat=[x1,x2;x3,x4] corresponds to the variables. My aim is to obtain the corresponding coefficient matrix as follows: [[0, -c, b, 0], [-b, a - d, 0, b], [c, 0, -a + d, -c], [0, c, -b, 0]] Is there any way to achieve this goal?
