Code to use to plot this vector

I have a vibration data.

File name, y_average with value:

 <40000 X 1 double>

Which code do I use to plot the signal with respect to time

the data was taken over 4 seconds.

doc plot

And, it would appear since 40k pts/4 sec, the sample rate was 10 kHz so to plot vs real time an t vector of same length.

doc colon doc linspace
