If you run Simulink from the GUI menu, then variables for To Workspace blocks go in to the base workspace.
If you run Simulink by using the sim() command, then variables for To Workspace blocks go in to the workspace of the function that you call sim() in.
If you need to pull a variable out of the base workspace you can do that using evalin()
a = evalin('base', 'a');
b = evalin('base', 'b');
new_state(a, b);

And did you call that with two arguments?
new_state(2,3)

Say you have variable a and b in the base workspace, then you can call
y = new_state(a,b);
If you want to call the new_state from within the function, you do not have direct access to the base workspace.
Perhaps it will best for you to open new question thread and better formulate your question (with more examples)?
