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.

OK, we'll check back later for the audio file.

在 MATLAB Online 中打开

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