Using specific routines in LAPACK library pacakge


How to run specific modules in LAPACK in a Fortran code?

With the title "Using LAPACK library in fortran codes" in this forum, it is clearly explained.


Use call option to find the solution for the A*X = B lenear equations using the routine DGESV

call DGESV()

Compile the code by

gfortran -o output codeName -L. -lliblapack


From LAPACK page, 

"DGESV computes the solution to a real system of linear equations
    A * X = B,
 where A is an N-by-N matrix and X and B are N-by-NRHS matrices.

 The LU decomposition with partial pivoting and row interchanges is
 used to factor A as
    A = P * L * U,
 where P is a permutation matrix, L is unit lower triangular, and U is
 upper triangular.  The factored form of A is then used to solve the
 system of equations A * X = B. "
