Displaying the elements of an array

Hi,

I have a problem with displaying the elements of an array. I try 2 approaches and getting 2 different results for the same thing. I have these variables and the loop

ext_freq = 640e6;              
sim = 1 / ext_freq;
period = 4500e-9;             
time1 = 0:sim:period;

When I say

disp(time1)

the last 4 elements of the array are

Columns 2878 through 2881

    0.4495    0.4497    0.4498    0.4500

But when I say

disp(time1(2881))

I got

4.5000e-06

I tried simpler arrays with the same logic and got the same results unlike here. I'd appreciate if you can explain me why there is such a difference here.

Thanks.

Look at the very beginning of the display. You will almost certainly see something like

1.0e-5 *

which is a scaling factor that is being applied to the entire display.

To avoid this, give the command

format long g

Yes, I missed that line. Thank you!
