SOFiA application example 1
In the first example we generate an ideal full audio spectrum unity plane wave of order N=9 impinging from Azimuth = pi/3 and Elevation = pi/3 to a rigid sphere array using W/G/C. We observe the array response in a single fft-bin using makeMTX and visual3D.
File(s)
Run `sofiaAE1.m`.
