Resetting a Time vector to zero

suppose I have the following time vector

x = [ 4 5 6 7 8 9 10 ]

I want it reset the vector to zero so I could use:

stepsize = x(2)-x(1)
newx = [ 0:stepsize:length(x)-1]

output:

0 1 2 3 4 5 6

Is there a faster way or more efficient way to do this in matlab?

newx=x-x(1)

x = [ 4.5 5.7 7.7 8.9 9.8 10.1 ]
newx=x-x(1)
newx =
       0    1.2000    3.2000    4.4000    5.3000    5.6000
