plot(t,y);

在 MATLAB Online 中打开

[y,fs] = audioread('Samuel_Pappalardo.wav')
t = (0:size(y,1)-1)/fs;
figure;
plot(t, y);

The above repairs a boundary condition in your time calculation.

It does not, however, repair any index problem. If you encountered an index problem it implies that you had an existing variable named plot or linspace or length
