Current Folder
Shows files available in the working directory.
Command History
Stores previously executed commands.
Your First MATLAB Commands
Basic arithmetic operations:
a = 10; b = 5; c = a + b d = a - b e = a * b f = a / b
MATLAB immediately displays the results.
Working with Variables
Variables store numerical data for calculations.
Voltage = 230; Current = 10; Power = Voltage * Current

Plotting Graphs in MATLAB
MATLAB is famous for its visualization capabilities.
t = 0:0.01:1; y = sin(2*pi*50*t); plot(t,y)
This generates a 50 Hz sine wave.
Electrical engineers frequently use plots for:
- Voltage Waveforms
- Current Waveforms
- Power Curves

Programming Basics in MATLAB
If Statement
Voltage = 230;
if Voltage > 220
disp('Voltage is High')
else
disp('Voltage is Normal')
end
For Loop
for i = 1:10
disp(i)
end
Programming is important for automation and advanced simulations.
