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

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?

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

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

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

As you can check:
1.2345678e7 - 1234567
ans =
0

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

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.
