Question

matlab help
When I put "t=logspace(-3,6,10)" on matlab, it says
1.0e+06*
0.0000 0.0000 0.0000 0.0000 0.0000 0.0001 0.0010 0.0100 0.1000 1.0000
I don't understand what 1.0e+06 means. Please, help

Answer 1

It's the scalefactor on your coefficients

Answer 2

1e6 means 1*10^6

Answer 3

One more thing, is it not that the first output is \(10^{-3}=0.001\) but the first output on the array is 0.0000, if we * whatever, we get 0
it confused me a lot

Answer 4

I would expect to see
>> t= logspace(-3,6,10)
t =

Columns 1 through 6:

1.0000e-03 1.0000e-02 1.0000e-01 1.0000e+00 1.0000e+01 1.0000e+02

Columns 7 through 10:

1.0000e+03 1.0000e+04 1.0000e+05 1.0000e+06

in matlab, you can redefine functions or "shadow" them.
as a check, do a
which logspace
and
help logspace
to be sure you are actually referencing the correct routine.

Answer 5

I show you what I got

Answer 6

also, you can do
format long
to see more decimals
1e-3 would be 1e6*1e-9

Answer 7

yes, it looks like it picked a scalefactor to get 1 as the last coefficient.

Answer 8

Thank you so much for "format long" I got the answer which makes sense to me.
