To plot the voltages of a three-phase alternating current with the given parameters in MATLAB, you can use the following code:
```
% Define the parameters
amplitude = 220; % V
frequency = 60; % Hz
phase_diff = 120; % degrees
% Define the time vector
t = linspace(0, 1/frequency, 1000);
% Calculate the voltages for each phase
phase_1 = amplitude * sin(2*pi*frequency*t);
phase_2 = amplitude * sin(2*pi*frequency*t - (phase_diff/360)*2*pi);
phase_3 = amplitude * sin(2*pi*frequency*t + (phase_diff/360)*2*pi);
% Plot the voltages for each phase
plot(t, phase_1, 'r', t, phase_2, 'g', t, phase_3, 'b');
xlabel('Time (s)');
ylabel('Voltage (V)');
legend('Phase 1', 'Phase 2', 'Phase 3');
title('Three-Phase AC Voltages');
```
This will create a plot with three lines, one for each phase, showing the voltage over time. The x-axis represents time in seconds, and the y-axis represents voltage in volts. The legend identifies which line corresponds to which phase, and the title describes what the plot represents.
