r8row, a FORTRAN90 code which contains utility routines for R8ROW's, that is, double precision real MxN arrays, considered as M row vectors, each of length N. The data may be thought of as a matrix of multiple rows, and many operations will be carried out rowwise.

r8row is available in a C version and a C++ version and a FORTRAN90 version and a MATLAB version and a Python version.
R8COL, a FORTRAN90 code which contains utility routines for R8COL's, that is, double precision real MxN arrays, considered as N column vectors, each of length M. The data may be thought of as a matrix of multiple columns, and many operations will be carried out columnwise.
R8GE, a FORTRAN90 code which contains linear algebra routines for R8GE matrices (real, 64 bit, General format).
R8LT, a FORTRAN90 code which contains linear algebra routines for R8UT matrices (real, 64 bit, lower triangular format).
R8UT, a FORTRAN90 code which contains linear algebra routines for R8UT matrices (real, 64 bit, upper triangular format).
