Convert an equation system to matrix form in Maxima

I have an equation system on the form:

eq1 : q = a*x+b*y;
eq2 : r = c*x+d*y;

I would like it to get the coefficient matrix, which in this simple case is:

T : matrix([a,b], [c,d]);

So that I can express the equation system as:

eq3 : Q = T . X;

Because I want to use T in further matrix operations. (The original equations are what I get from my problem and I don't want to turn them into matrix form manually, as that's what this kind of program is for. But I just can't figure it out)

Solution

  • I think you want coefmatrix and augcoefmatrix.
