New on CTAN: diffcoeff

Andrew Parsloe submitted the diffcoeff package. Version: 1.0 2016-06-27 License: gpl2 Summary description: Write differential coefficients easily Announcement text:
diffcoeff.sty enables the easy writing of ordinary and partial differential coefficients of arbitrary order. For mixed partials, the overall order (algebraic or numeric) is calculated by the package. Optional arguments specify points of evaluation / variables held constant, and the placement of the differentiand (numerator / appended). Key = value settings tweak the display. Further commands construct analogous coefficients from D, \Delta, and \delta, and write Jacobians. Also included is diffcoeffx.sty which is diffcoeff.sty on steroids. The package's use expl3 and xparse from the LaTeX3 bundles, l3kernel and l3package's.
The package's Catalogue entry can be viewed at http://www.ctan.org/pkg/diffcoeff The package's files themselves can be inspected at http://mirror.ctan.org/macros/latex/contrib/diffcoeff/

diffcoeff – Write differential coefficients easily and consistently

diffcoeff.sty allows the easy and consistent writing of ordinary, partial and other derivatives of arbitrary (algebraic or numeric) order. For mixed partial derivatives, the total order of differentiation is calculated by the package. Optional arguments allow specification of points of evaluation (ordinary derivatives), or variables held constant (partial derivatives), and the placement of the differentiand (numerator or appended).

The package is built on xtemplate, allowing systematic fine-tuning of the display and generation and use of variant forms (like derivatives built from D, \Delta or \delta). A command for differentials ensures the dx used in e.g. integrals is consistent with the form used in derivatives.

The package requires the 3 bundles l3kernel and l3packages.
