This is my code:
function outputSpectrogram(input)
[audio, fs] = audioread('asianelephantspeaker.wav');
audioMono = (audio(:, 1) + audio(:, 2)) / 2;
spectrogram(audio, 256, [], 25, 2000, 'yaxis');
title('rumble')
end
The error is like this "outputspectrogram
Error using spectrogram>chkinput (line 252)
X must be a vector (either row or column).
Error in spectrogram (line 166)
chkinput(x);
Error in outputspectrogram (line 5)
spectrogram(audio, 256, [], 25, 2000, 'yaxis');
>> "
How i will rectify this error?
and I will also attach my audio with this.

audioMono = (audio(:, 1) + audio(:, 2)) / 2;
spectrogram(audioMono, 256, [], 25, 2000, 'yaxis');
% ^^^^ the "Mono" was missing
