What do you mean?

Abdulaziz AlKuwari 2014-1-27

Let the A matrix for example to be A = [X Y, Q Z] If I entered the symbols and tried to transfer the State space representation of the model to a transfer Function, MATLAB will generate an error saying that X, Y,and Z are not defined. I need yo move from state space to transfer function symbolically (without initializing X, Y, Z,..)

I Wish it is clear

Symbolic representation is not compatible with the controls tools. You would have to do this manually.
