Code by Kevin Rhoads to allow precision to be deliberately thrown away in an IEEE floating point compliant computing environment in order to more closely model computations in less precise floating point systems.

Fortran 90 codes to integrate Ito stochastic differential equations, generate random numbers, compute the FFT, and time programs.

Fortran Portability Project, Fortran 2003 examples, and Fortran modules.

Code from the book, translated to ELF, a Fortran 90 subset. Algorithms for calculations in science and engineering, including linear equations, spline interpolation, integration, differential equations, zero finding, minimization and singular value de...

Fortran 77/90/95 codes to test run-time diagnostic/debug capability of Windows and Linux Fortran Compilers, by Arnaud Desitter and Herman D. Knoble.

Generation of subsets and permutations, Hamiltonian cycles, determinants and permanents, network flow, and minimum spanning trees.

Links to chemistry, physics, and engineering codes, many in Fortran.

Chksys.f determines the properties of the run-time environment for Fortran 77 programs. Chkcomp.f is a Fortran 77 code containing deliberate deviations from the standard and deliberate bad statements for testing the compiler's accuracy. Chksysff.f90 i...

SPARSEM is a collection of sparse matrix classes that makes programming with sparse matrices (and large problems) almost as easy as a matrix language. BLUPF90 is a BLUP program written using SPARSEM. REMLF90 is a REML version of BLUPF90 that uses acce...

Codes to time floating point and integer arithmetic, intrinsic functions, and random access to memory.
