The main program is main_directivity_analysis.m.

The user types the sound pressure levels, coordinates of the microphones, and sets the processing variables into the program

The program then calculates the sound power level and analyzes the source directivity from the entered measured sound pressure levels (dB) on a hemispherical or spherical surface.

There are two testing programs included: test_directivity_Analysis_monopole.m and test_directivity_Analysis_dipole.m. These programs are for simulating monopoles adn dipoles and calculating the theoretical sound power levels and estimating the amount of integration error.

The directivity is analyzed using Taylor series. An error term has been derived for estimating the integration error of the sound power estimation. This error estimate is shown in the output variable LL. See section Output Variables in the program
main_directivity_analysis.m for more details.
