Hi everyone,

I want to simulate the following two circuits in Multisim:

The voltages on nodes 1, 2 and 3 should 80V, -64V and 156V respectively.

But in Multisim:

And if it's possible, guide me to any site or textbook showing how to simulate circuits in MATLAB or Simulink.

 

Your Multisim circuit is not the same as your original diagram.
Ix current is a current that is flow through 4 ohm's resistor. But in Multisim I2 where is flowing ?

 

Isn't connected to 4 ohm's resistor? Please bear with me, I'm new to Multisim.

 

I think what Jony means is that the IZ control input of the current-controlled current-source must be in series with R3. You have it in parallel (effectively shorting out R3).

If you post a larger graphic (not JPEG) of the circuit, it will be easier to see. Your posted circuit is rather fuzzy.

 

This is the graphic:

Your I2 is in parallel with R2 which was wrong. I2 should be in series with R2.

This is what Jony130 was saying.

You do understand the difference between series and parallel, don't you?
