Code by John H. Matthews to accompany the book Numerical Methods for Mathematics, Science, and Engineering, Second Edition.

Modification of known Gauss method for pivot element elimination that uses internal rows-transposition-vector and works with matrix strictly "col-by-col". The algorithm factorizes the source matrix so that created factor-matrix may be used several tim...

Analogue data is collected and digitized with an A/D converter. Having then a collection of digitized time series which reside in the computer, this program calculate amplitude density, autospectral (power) density and cross-spectral density functions...

Given a function coded in Fortran, GRAD produces Fortran code to compute the derivatives with respect to specified variables (i.e. the GRADient). The MS DOS binaries can be downloaded freely.
