The purpose of this program is to find the solution of Ax=b using conjugate gradients algorithm.
  The i/o functions are in one file "kaio.c".//stands for "kai's i/o".
  The conjugate gradient algorithm function is in the file "cgaf.c"
  gsl_blas library is used here to make this program
  the test file is "sample.txt"
How to Use:

the output is saved in the file "out.txt"
[kaixiany@gradient1 kaixian_hw12]$ ./kaixian_HW12 <sample.txt
Here is the solution of the equation Ax=b : 
524.686646
-177.434601
446.189697
109.816742
-730.670654
