Hi,

When I was using the dsp.aoa_capon() function for angle of arrival estimation, I met the “singular matrix” problem raised by the np.linalg.inv() function. Does any body know how to solve or prevent this problem? How did the “singular matrix” problem happen? May I use dsp.aoa_bartlett() to replace dsp.aoa_capon()? Are the two beamforming functions compatible?
