LAPACK_OSX is available in a FORTRAN90 version.
BLAS, a FORTRAN90 library which contains the Basic Linear Algebra Subprograms (BLAS) for level 1 (vector-vector operations), level 2 (matrix-vector operations) and level 3 (matrix-matrix operations), for single precision real arithmetic, double precision real arithmetic, single precision complex arithmetic, and double precision complex arithmetic.
LAPACK_D, a FORTRAN90 library which is a FORTRAN90 version of the double precision real LAPACK + BLAS libraries.
LAPACK_F77, a FORTRAN90 program which calls the FORTRAN77 version of the LAPACK + BLAS libraries.
LAPACK_S, a FORTRAN90 library which is a FORTRAN90 version of the single precision real LAPACK + BLAS libraries.
