Why are my vectors different lengths?

load 'gong.mat'     %Returns sampling frequency Fs and data y
T=1/Fs;             %Sampling period
L=1*y;             %Number of samples
t=(0:L)*T;        %Time vector.
plot(t,y);

I am trying to plot an audio file (gong crash) and am receiving an error in the final line. The error is "Vectors must be the same length." To my understanding, I am compensating for their length by scaling the time vector by dividing by the sampling frequency "Fs."

Thank you for your time and expertise.

Answer 1

t = T*(1:numel(y));

Answer 2

L=1*y;             %Number of samples

No. 1*y is the same as y. You did not show how y is defined, by I guess that you want:

L = size(y, 1)
% or
L = size(y, 2)

numel(y) works also, if y is a mono signal, but not for stereo. As Stephen has mentioned already, you have to start at the frame 1, not 0: "1:L" instead of "0:L".
