Fox co-authored a technical report on the PORT library in numerical computing.
On September 5, 1978, Phyllis Fox co-authored a significant technical report titled "A portable library of FORTRAN subroutines," which played a vital role in the dissemination of the PORT numerical library. This library became a foundation in numerical computation, known for its portability and reliability, thus enhancing the capacity for scientific computing in different environments and making advanced computational techniques more widely accessible.
