How to concatenate 2 time series that both start from zero?

Hi all

How to concatenate 2 time series that both start from zero? Given that both of them have the same time step? Example :

t1=[0,1,2,3] 
t2=[0,1,2] 

Output

T=[0,1,2,3,4,5]

[Ajay Kumar]

could you elaborate the problem statement and expected output?

I added an example to the question body

[Akira Agata]

Sounds like T = [t1,max(t1)+t2(2:end)].

But could you tell us what is your purpose to create this output? Because, at this time, I have no idea how to utilize this output vector T.

Thank you that worked great !

this is a time series that correlates another variable that changes with time, anything you can immagine, temperature, displacement , velocity. and since that variable is measured in different times , each time , the t variable starts from zero , but now I wanted to plot the whole together

there is one problem now , that since the t2(2:end) starts from the second member, then the total t with have one member less that the total members of the function variable , let's say the velocity
