# SYNOPSIS
#
# AX_BLAS([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
#
# DESCRIPTION
#
# This macro looks for a library that implements the BLAS linear-algebra
# interface (see http://www.netlib.org/blas/). On success, it sets the
# BLAS_LIBS output variable to hold the requisite library linkages.
#
# To link with BLAS, you should link with:
#
# $BLAS_LIBS $LIBS $FLIBS
#
# in that order. FLIBS is the output variable of the
# AC_F77_LIBRARY_LDFLAGS macro (called if necessary by AX_BLAS), and is
# sometimes necessary in order to link with F77 libraries. Users will also
# need to use AC_F77_DUMMY_MAIN (see the autoconf manual), for the same
# reason.
#
# Many libraries are searched for, from ATLAS to CXML to ESSL. The user
# may also use --with-blas=<lib> in order to use some specific BLAS
# library <lib>. In order to link successfully, however, be aware that you
# will probably need to use the same Fortran compiler (which can be set
# via the F77 env. var.) as was used to compile the BLAS library.
#
# ACTION-IF-FOUND is a list of shell commands to run if a BLAS library is
# found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it is
# not found. If ACTION-IF-FOUND is not specified, the default action will
# define HAVE_BLAS.

# AX_LAPACK([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
#
# DESCRIPTION
#
# This macro looks for a library that implements the LAPACK linear-algebra
# interface (see http://www.netlib.org/lapack/). On success, it sets the
# LAPACK_LIBS output variable to hold the requisite library linkages.
#
# To link with LAPACK, you should link with:
#
# $LAPACK_LIBS $BLAS_LIBS $LIBS $FLIBS
#
# in that order. BLAS_LIBS is the output variable of the AX_BLAS macro,
# called automatically. FLIBS is the output variable of the
# AC_F77_LIBRARY_LDFLAGS macro (called if necessary by AX_BLAS), and is
# sometimes necessary in order to link with F77 libraries. Users will also
# need to use AC_F77_DUMMY_MAIN (see the autoconf manual), for the same
# reason.
#
# The user may also use --with-lapack=<lib> in order to use some specific
# LAPACK library <lib>. In order to link successfully, however, be aware
# that you will probably need to use the same Fortran compiler (which can
# be set via the F77 env. var.) as was used to compile the LAPACK and BLAS
# libraries.
#
# ACTION-IF-FOUND is a list of shell commands to run if a LAPACK library
# is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
# is not found. If ACTION-IF-FOUND is not specified, the default action
# will define HAVE_LAPACK.
