MODULE
A FORTRAN90 Makefile Example Using a Module

MODULE is an example of how a makefile can be used to manage a set of FORTRAN90 files that includes a module.

The makefile management all these files is

• makefile contains the makefile for managing these files.

The underlying task is to set up and manipulate a single precision general matrix, whose type is nicknamed "SGE". A module summarizes certain information about the SGE matrix. The routines available to manipulate the SGE matrix include:

• sge_module.f90 contains the FORTRAN90 module.
• sge_create.f90 used to create a new SGE matrix.
• sge_delete.f90 used to delete an SGE matrix.
• sge_det.f90 used to compute the determinant of an SGE matrix.
• sge_fa.f90 factors an SGE matrix.
• sge_sl.f90 solves a linear system associated with a factored SGE matrix.
• sge_slt.f90 solves a linear system associated with the transpose of a factored SGE matrix.

Several utility routines are included:

• r_swap.f90 swaps two real values.
• rvec_print.f90 prints a real vector.
• timestamp.f90 prints the current YMDHMS date as a timestamp.

SGE_MOD_PRB.F90 is a sample program that calls the routines to set up, factor and solve a linear system.

• sge_mod_prb.f90 contains the output from a run of the compiled program.
• sge_mod_prb_output.txt the output file.
