Hello,
My problem concerns the use of BeamformerDamas.
I'm following the example 'Airfoil in open jet', and everything works fine in my workstation.

But when I'm trying to implement a custom problem (grid 61 x 61, 120 mics, 5 sec of signals at 204kHz), It doesn't works (the script runs more than 10min without results).

```
CSM = PowerSpectra(
    time_data=signals,
    window='Hanning', overlap='50%', block_size=nperseg,
    ind_low=ind_low, ind_high=ind_high,
)
beams = BeamformerBase(freq_data=CSM, steer=st, r_diag=False)
damas = BeamformerDamas(beamformer=beams, n_iter=100)
```

However, the BeamformerBase output is correct.
Perhaps someone has encountered the same problem ?

Many thanks,

Hugo Demontis

Ok, I am able to run my script.

For DAMAS, please set the arg "calcmode" to "full" !
