How do I convert a multichannel .mat to .wav

I would like to convert a 2 x 24 channel binaural room impulse response (BRIR) for Atmos into .wav audio file.

I am a Matlab illiterate and could not get audiowrite to do it.

This is the format of the BRIR:

brir 65536x2x24 double 65536x2x24 double

After some trying I ended up with

audiowrite('/MATLAB Drive/angle_0.wav', brir, Fs, 'BitsPerSample',nBits, 'Comment','Surrey BRIR Azimut0');

Error using audiowrite

Data must be a 1-D or 2-D numeric array.

How can I do it?

First reshape brir to a 2-D array:

 brir = reshape(brir,size(brir,1),[]);
 audiowrite('/MATLAB Drive/angle_0.wav', brir, Fs, 'BitsPerSample',nBits, 'Comment','Surrey BRIR Azimut0');
