Easy Simulink Questions (new user)

Hi,

I am a new user to Simulink (and in some respects Matlab). I have a couple of question regarding the program I was hoping you could clear up.

1. Is there a simple way of converting a block diagram model of a system into Matlab code and vice versa?

2. If I have say a variable psi and when I multiply this by Vt I get another variable Yrdot can I represent this in simulink using a gain block or do you have to use the multiplication block?

3. Finally, how do you create a system within a system? I've tried using the block for it but I can't connect any input or out from it.

Thanks,

J

1. You cannot convert between Block Diagram and MATLAB-Code (.m file)

2) PSI (being cvariable) would be connected to a gain block with Vt defined in the workspace or in the block directly as a number

3) You need to use inports and outports to add more connections to a subsystem.

Thanks.
