README file for LaTeX package: diffcoeff
Author: Andrew Parsloe (aparsloe@clear.net.nz) 2016-06-27
diffcoeff.sty allows the easy writing of ordinary and partial differential
coefficients of arbitrary order. For mixed partial derivatives, the overall
order (algebraic or numeric) is calculated by the package. Optional arguments
allow the easy specification of a point of evaluation for ordinary
derivatives, or variables held constant for partial derivatives, and the
placement of the differentiand (in the numerator or appended). Some tweaking
of the display is possible through key = value settings. Secondary commands
provide analogous coefficients constructed from D, \Delta and \delta and a
command for writing Jacobians.
diffcoeffx.sty is diffcoeff.sty 'on steroids', extending that package in ways
that are probably unnecessary but have a certain logical forece.
The packages require the LaTeX3 bundles, l3kernel and l3packages.
There are six files plus this README: diffcoeff.tex, diffcoeff.pdf (compiled
from diffcoeff.tex), and diffcoeff.sty; and diffcoeffx.tex, diffcoeffx.pdf
and diffcoeffx.sty. The tex and pdf files should be placed in texmf/doc/
latex/diff, and the sty files in texmf/tex/latex/diff.
