state space to transfer function conversion

   dx/dt = A x+  B q +  E u

   y  = C x+ D q  +  F u

the above is a state space representation of my model

where x -states

       u-input

       q- disturbance /load

A,B,C,D,E,F corresponding coefficient matrices

how to convert this state space representation to transfer function

[Azzi Abdelmalek]

Your system can be written as

dx=C.x+B1.e       % With e=[q;u] and B1=[B E]
y=C.x+D1.e        % With D1=[D F]

Then Use ss2tf as usually.
