program block diagram in matlab, not simulink
Hi,
I have an task to calculate the transferfunction with an given, complicated block diagram. So I simplify the block diagram until I have the complete transfer function in the last block – not a problem. Now I have the next task which tells me to proof that my previous calculations are correct using matlab (not simulink, which would be the third task; and I have already done that to make sure my transfer function from task a) was correct)
So my question is: how do I translate a block diagram with given transfer functions into matlab code? I can easily define all the blocks’ transfer functions like G1=tf(c1,d1);, but how do I tell matlab in code where a sum is, where a branch splits etc?
I would realy appreciate any help, as that is something our professor does not show in his vids and leaves to our own to figure out -.-
Thank you very much,
