1. The problem involves analyzing a circuit with resistors, current sources, voltage sources, and dependent sources labeled 4I_x and 2V_x. 2. To solve this circuit using MATLAB, we typically use methods like nodal analysis or mesh analysis. 3. First, define the node voltages $V_1, V_2, V_3, V_4$ and currents $I_o, I_x$ as variables. 4. Write the Kirchhoff's Current Law (KCL) equations at each node considering all currents entering and leaving the node. 5. Express dependent sources in terms of controlling variables: $4I_x$ and $2V_x$. 6. Formulate the system of linear equations in matrix form $A\mathbf{x} = \mathbf{b}$, where $\mathbf{x}$ contains unknown voltages and currents. 7. Use MATLAB commands like \texttt{A = [...]; b = [...]; x = A\b;} to solve for unknowns. 8. Interpret the solution vector $\mathbf{x}$ to find the values of $V_1, V_2, V_3, V_4, I_o, I_x$. Since the problem is to solve the circuit using MATLAB, the key step is setting up the equations correctly and then using MATLAB's linear solver. Final answer: The solution vector $\mathbf{x}$ obtained from MATLAB gives all node voltages and currents in the circuit.
