*  matrix A:

*
*  Description.
*  ============
*
*  The routine computes all eigenvalues and, optionally, eigenvectors of an
*  n-by-n real symmetric matrix A. The eigenvector v(j) of A satisfies
*
*  A*v(j) = lambda(j)*v(j)
*
*  where lambda(j) is its eigenvalue. The computed eigenvectors are
*  orthonormal.

将上面代码存储为： ex_dsyev.f

2. 下载lapack-3.11：

wget .

3. 解压lapack并copy make.inc：

tar zxvf v3.
cd lapack-3.11
cp ample make.inc

并且编辑 lapack-3.11/make.inc，将其中的-O3 -O2等等，改成-g

编译lapack-3.11/Makefile，将其中

lib: lapacklib tmglib
修改为：
lib:  blaslib variants lapacklib tmglib lapackelib lapacke_example
 

4. 编译lapack：

make -j

5. 安装lapack lib：

cp LAPACKE/include/*.h /home/hipper/ex/ex_fortran/sdk_lapack/include/
cp *.a /home/hipper/ex/ex_fortran/sdk_lapack/lib/

 其中的*.a 如下：

liblapack.a  liblapacke.a  librefblas.a  libtmglib.a

6. 编译fortran示例：

gfortran -g ex_dsyev.f -L /home/hipper/ex/ex_fortran/sdk_lapack/lib/ -llapack -lrefblas

7. 运行：
