However, as it turned out, the 1980s were fertile years for the "black box" side, yielding important libraries such as BLAS and LAPACK, and integrated environments like MATLAB and Mathematica. By the early 1990s, when Second Edition versions of "Numerical Recipes" (with code in C, Fortran-77, and Fortran-90) were published, it was clear that the constituency for "Numerical Recipes" was by no means the majority of scientists doing computation, but only that slice that lived "between" the more mathematical numerical analysts and the larger community using integrated environments. The Second Edition versions occupied a stable role in this niche environment.
