I've simulated DOA MUSIC algorithm. suppose given 30, 60 and 70 in degrees. how can i get the estimated angles in music algorithm?

I think there are only approximations. There is no fixed code to calculate the settings in which this technique works.

Not sure I understand exactly what you question, are you saying you have a MUSIC spectrum and want to find the peak location? If so, you can use findpeaks function.

Alternatively, if you have access to Phased Array System Toolbox, there is an off the shelf MUSIC algorithm to use. See the reference page below

Reason i needed the estimated peak points is that i wanna calculate and plot the root mean square error (RMSE) of MUSIC and MVDR algorithm versus SNR. can you please help me?
Atteched MUSIC and MVDR matlab code.
