Welcome to fpm-linalg

This is the documentation of the fpm package linalg: a light-weight Fortran package for linear algebra.

Installation

The package is installed with the Fortran package manger fpm:

fpm build

Before compilation, the compiler and the compiler flags can be set by defining the environment variables FPM_FC and FPM_FFLAGS, respectively (see also the source files export_gfortran.sh and export_ifx.sh).

Quad precision is activated by adding the flag -DQUAD to the FPM_FFLAGS environment variable.

To use this package as a dependency in another fpm project, add the following to the fpm.toml file:

[dependencies]
linalg = { git="https://gitlab.com/thomas.biekoetter/fpm-linalg" }

Test

The package has been developed and tested using the gnu gfortran and the intel ifx compilers.

You can run the test routines with:

fpm test

Example

An example program that uses the linalg package can be found in the folder app. You can run this program with:

fpm run
