This is annotated by PYTHON_VERSIONS_INCOMPATIBLE= 33 # not yet ported as of x.y.z or PYTHON_VERSIONS_INCOMPATIBLE= 33 # py-foo, py-bar respectively, please use the same style for other packages, and check during updates. Use versioned_dependencies.mk where applicable. Use REPLACE_PYTHON instead of handcoded alternatives, where applicable. Reorder Makefile sections into standard order, where applicable. Remove PYTHON_VERSIONS_INCLUDE_3X lines since that will be default with the next commit. Whitespace cleanups and other nits corrected, where necessary. 2012-09-11T23:04:15Z asau asau@pkgsrc.org 2012-09-11T23:04:15Z urn:sha1:b0feb9f5b186a62a131121fe59db9ccdc0a844bd 2012-04-08T19:08:44Z wiz wiz@pkgsrc.org 2012-04-08T19:08:44Z urn:sha1:4faa20286079b6833043b7bbd12c0e72039551f6 Remove devel/py-ctypes (only needed by and supporting python24). Remove PYTHON_VERSIONS_ACCEPTED and PYTHON_VERSIONS_INCOMPATIBLE lines that just mirror defaults now.

Pkgsrc changes: * Set LICENSE * correct EOL style of installed files * Add self-test target Changes: --0.14-- Released February 5, 2010 General changes: * Fully separated the code into "low-level" and "high-level", permitting the use of alternative contexts (the mpmath.mp object provides the default implementation) * Implemented a context for fast double-precision arithmetic using Python types (mpmath.fp) * Implemented hooks for importing a faster version of mp arithmetic from Sage * Implemented optimized fp versions of certain functions (including erf, erfc, gamma, digamma, ei, e1) * Renamed and reorganized various internal modules and methods (including merging low-level modules into mpmath.libmp). This should not affect most external code using top-level imports. Plotting: * Implemented splot() for 3D surface plots (contributed by Jorn Baayen) * Permit calling plot functions with custom axes (contributed by Jorn Baayen) Matrices: * Fixed lu_solve for overdetermined systems (contributed by Vinzent Steinberg) * Added conjugate matrix transpose (contributed by Vinzent Steinberg) * Implemented matrix functions (expm, cosm, sinm, sqrtm, logm, powm) Miscellaneous: * Prettier printing of numbers with leading zeros at small precisions * Made nstr pass on kwargs, permitting more formatting options * Fixed wrong directed rounding of addition of numbers with large magnitude differences * Fixed several docstring typos (contributed by Chris Smith) * Fixed a bug that prevented caching of quadrature nodes to work optimally. Special functions: * Implemented fast evaluation for large imaginary heights of the Riemann zeta function, Z function and derived functions using the Riemann-Siegel (contributed by Juan Arias de Reyna) * Unified the zeta() and hurwitz() functions, automatically selecting a fast algorithm * Improved altzeta() to fall back to zeta() for large arguments * Fixed accuracy of zeta(s) for s ~= 1 * Implemented exact evaluation of Euler numbers (contributed by Juan Arias de Reyna) * Implemented numerical evaluation of Euler numbers and Euler polynomials (eulernum(), eulerpoly()) * Fixed bernpoly() and eulerpoly() to compute accurate values for large parameters * Fixed accuracy problems for hypergeometric functions with large parameters * Faster evaluation of hypergeometric series using on-the-fly code generation * Optimized hypercomb to detect certain zero terms symbolically * Removed the djtheta function (jtheta() accepts a derivative parameter) * Implemented li(x, offset=True) to compute the offset logarithmic integral * Fixed wrong branch in Lambert W function for certain complex inputs * Implemented the reflection formula for the Barnes G-function, superfactorials, hyperfactorials, permitting large arguments in the left half-plane * Implemented analytic continuation to |z| >= 1 for hypergeometric functions pFq with p=q+1; added hyp3f2() * Implemented Borel summation of divergent pFq functions with p > q+1 * Implemented automatic degree reduction of hypergeometric functions with repeated parameters * Added convenience functions expj(), expjpi() * Use Mathematica's convention for the continuation of the Meijer G-function * Added phase(), polar(), rect() functions for compatibility with the Python 2.6 cmath module * Implemented spherical harmonics (spherharm()) * Optimized ci(), si(), chi(), shi() for complex arguments by evaluating them in terms of ei() * Optimized hyp2f1 for z ~= -1 2010-01-27T14:16:10Z drochner drochner@pkgsrc.org 2010-01-27T14:16:10Z urn:sha1:5e50301277529398daeb085231601d306c78fe4d
