Abstract: We present the solution of the general linear system in n coquaternionic variables and m equations, and derive the Kronecker product from the matrix system AXB in coquaternions. It is shown, that the coquaternionic Kronecker product can be computed by means of dyadic coquaternionic products. The special matrix case Ax = b is also included. The one dimensional case, including Sylvester’s equation is solved and there are several, nontrivial, numerical examples.
