Time vector for seismic plot

How do I create a time vector? Im supposed to create a time vector so that I can plot a seismogram

my sampling frequency is 40 Hz a

the sample interval in in a file called sachdr.delta

it starts at 0 seconds

I just don't understand how to include all of these parameters in to make the time vector work. I am going to plot this time vector as the x variable is and the amplitdue (y variable) is called utahz.

Can you transfer your variables to excel or matlab(variable table) from your file ?

I was able to look at the file and it only contains the number 0.025

I tried:

Fs = 40;

Ts = 1/ 40;

ts = 0:Ts:0.0250;

and then

plot(ts,utahz) but it threw me an error saying that the vectors were not the same length

[Hakan Sagir]

1/40 = 0.025 already,

if you try to get the vector,

your code is like this ts = 0:0.250:0.0250

it already gives you the vector ts = [0 0.0250] only 2 variables

you have something wrong in your data or you get it wrong maybe :)

I looked at how many reading the utahz vector had (80683) then I multiplied that by 0.0250

tl = linespace(0,2017.075,80683)

plot(tl,utahz)

Thank you!
