This list of 20 MATLAB projects ideas range over some of the solutions that use or can use MATLAB. After all, the list of applications of such a software is endless.

Audio Compression using Wavelets in MATLAB

Audio frequencies range from 20Hz to 20kHz but these frequencies are not heard in the same way. Frequencies below 20Hz and above 20kHz are very difficult to hear, while those not much more than 20Hz, or not much less than 20kHz, cannot be heard by most people. We often need to process these audio signals for various applications. MATLAB is one of the best signal analysis and signal processing tools.

Audio compression is a very good example of speech and signal processing. We use the Internet for various purposes including entertainment. Audio is common in all entertainment applications. If an audio file size is large, it takes more space to store.

Audio/video compression frees up space substantially, which can then be utilised for other purposes. This article describes some important audio compression techniques.

Huffman algorithm is a popular encoding method used in electronics communication systems. It is widely used in all the mainstream compression formats that you might encounter. The MATLAB project presented here encodes and decodes the information and also outputs the values of entropy, efficiency and frequency probabilities of characters present in the data stream.

Artificial Neural Network Simulation

Artificial neural network, in essence, is an attempt to simulate the brain. When the user enters the inputs (say, p1, p2 and p3) and the expected corresponding outputs (say, t1, t2 and t3) in the program, the program trains the system and gives a final weight. The final weight is computed to get the final expected output. This program is an attempt to understand the basics of artificial neural network and how one can use it for further applications.

Analogue Clock

NASA might get a fancy digital-count display, retire the analogue clock from Apollo era but the passion for the analogue clock does not end. An analogue clock has moving hands. The smaller (hours) hand and travels 30° in one hour whereas the longer (minutes) hand travels 360° in an hour. The seconds hand rotates with a step of 6°. Using this in MATLAB, you could design this for yourself. MATLAB has a good collection of graphics commands for plotting and analysing complex signals.

This next project helps count the number of people present in a meeting hall or classroom at a time. The program logic is also applicable in other applications including automatic temperature control which depends on the number of persons in a room. Video camera plays a very important role in this project.

Armature Controlled D.C Motor

Using MATLAB, this project employs armature control method for DC motors. The voltage applied to the armature circuit of the motor is changed by keeping the voltage supplied to the field circuit of the motor constant. However, there are many other methods that can be used to control the speed of the DC motor. The voltage control method changes the voltage to control the speed of the motor, whereas the flux control method makes changes in the flux. Another method is rheostatic control in which the rheostat variations control the speed.
