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
