I have a set of 3 symbolic and linear equations, like these:

eq1 = A11*U1+A12*U2+A13*U3=0
eq2 = A21*U1+A22*U2+A23*U3=0
eq3 = A31*U1+A32*U2+A33*U3=0

In matlab I use the command "equationsToMatrix" to get the system in the
form of matrices [Aij]*[Ui]=[0]

Is there any equivalent command or an easy way to do that with octave?

We should add such a command in the symbolic package.  I've filed a bug:

Would you like to help?  Your example would be a nice test case!
