The program is used to compute the gradient and hessian of the function.

The number of A,B,C can be changed in header.h A is for the value of function,B for the gradient and C for the Hessian.(0 means not to evaluate, 1 means to evaluate)

All the derivative are made by mathematicas.  
  
I tested this program with x.vec given in the website, 2 or 3 numbers have a little different with the answer given in the webpage, but error is less than 5%, I think that is acceptable, others are the same as the answer provided.

I tested with y.vec which has 2 vectors, it seems work well.

sample:
[kaixiany@galois20 kaixian_hw13]$ ./kaixian_HW13 < x.vec
the vector is:
4
1.200000
3.400000
4.500000
6.700000
f=:0.113663
the value of the function is : 0.113663
the value of df is :
4
-0.439235
-1.392520
2.148202
3.095136
the value of ddf is :
4	4
-0.868507
-2.185992
-2.307843
0.000000
-2.102134
-11.495951
-7.010811
2.911143
-2.307843
-6.957304
14.475872
19.662325
0.000000
2.911143
19.662325
14.699325
the time of this function ran is 0.000000
the number of f,df,ddf are called is 1
