1.Just download the file.
2. Extract it. I twould have 2 files names beampattern.m and polardb.m
3. Copy both files in your mathlab bin folder.
4. Open the matlab and open both files in mathlab editor.
5. Click on run
6. On workspace give the parameters, for example beampattern (5,0.5,[1 1 1 1 1]);
7. Enjoy looking the beampattern !

Good Luck !

HI.
Could you explain what does 'd' mean??
In the code, 'd' stands for 'INTER-ELEMENT SPACINGS B/W ELEMENTS'. But I do not know what it does mean exactly. What is the relation between 'd' and 'lambda' which is the wavelength.

In addition, what is the 'steer_angle'??
Could you explain more detail?
