problem with the min function or the 1.8509e+007 ??

Hello everybody I have a vector with three input values so this is how my vector is :

F=[ss(60,57) ;ss(13,57) ;ss(14,57)]

 F(1)

ans =

    18471736

>> F(2)

ans =

1.8509e+007

>> F(3)

ans =

    23963413

So i called the min function as this : [C,I]=min(F); >> C

C =

   18471736

>> I

I =

     1

Does 18471736 inf to 1.8509e+007

Answer 1

[Matt Fig]

There is no problem that I can see.

Yes, 1.847e7 is less than 1.851e7 and 2.396e7. Why would you expect anything else?

[Mariem Harmassi]

This is the three values 18471736,1.8509e+007,23963413 but what about the 'e' number ??

[Matt Fig]

The 'e' in 1.8509e+007 is short for '10^'. This is called scientific notation.

[Mariem Harmassi]

1.8509e+007 this notation is equivalent to 1.8509 * 10^007 ??

[Walter Roberson]

Yes.

[Matt Fig]

As you can check:

1.2345678e7 - 1234567
ans =

        0

Answer 2

[Walter Roberson]

Yes. 1.8509e+007 is approximately 18509000

[Mariem Harmassi]

its impossible cauz the three number are 3 by one dissimilarties between face images so The second one is the same person as the one compared to it so logically the second value must be the minimum

[Matt Fig]

Mariem, I would venture to guess that you have just learned that MATLAB, like any other language, does exactly what you tell it to do, not what you want it to do.

[Mariem Harmassi]

Thank u Matt , i know this it means that i should analyse the code there is an error not this one but perhaps another :/

[Mariem Harmassi]

Don't underestimate human stupidity especially the one executed by machine ;ppp I am searching for this stupidity ordered :p
