Hello!
My code is getting points like 5e-9 and i am putting these points on a vector. However after i run it i get a vector full of zeros.
Is there anyway to keep the real numbers in the vector.
Thank you

The small numbers are there, but not displayed. (My guess.) Try
>> format long
>> a = [1e9,1e-9]
a =
1.0e+09 *
1.000000000000000 0.000000000000000
>> a(2)
ans =
1.000000000000000e-09
>>
