How can i create a large colum variable with continious step?

Hey guys, I'm new to MatLab so this might be a basic question.

I need to make a plot of a blasting vibration. The data i posses to plot on the Y-axis includes 500 000 values. On the X-axis I need to plot the time. It must include 500 000 values with a continious step of 0,005s.

So i'm guessing i need some kind of loop to make a variable with 1 colum that looks like t=[0 0,005 0,010 0,015 0,020....]

Anyone knows how i can create this in Maple?

Thanks in advance!

You don't need a loop, you can use Matlab's colon operator to define a range of values first_value:step_size:last_value. You can also use linspace(first_value, last_value, Npoints).

y  = rand(1, 500000); % fake some data

 Npoints = numel(y);
 delta = 0.005;
 x_max = delta*Npoints - delta;
 x = 0:delta:x_max;

or

 x = linspace(0, x_max, Npoints);
