Lose of Precision when storing values
显示 更早的评论
I would like to store values into a 1x50 double array, but I loose precision where everything is stored in e+07. Is there a way to overcome this and store the full numbers?

What do you mean, you loose precision? I guess you mean the numbers displayed in the command window, such as
x=[1e7 1.1]
x =
1.0e+07 *
1.0000 0.0000
No worries here, of course the second value is still 1.1, it's just not displayed:
>> x(2)
ans =
1.1000
If you want to get more digits displayed, check out the format function:
>> format long
>> x=[1e7 1.1]
x =
1.0e+07 *
1.000000000000000 0.000000110000000
Hope this helps!

I tend to use
format long g
which avoids scientific notation as much as possible.
