 Module Name:   pkgsrc
 Committed By:  obache

 Modified Files:
        pkgsrc/math/py-mpmath: Makefile PLIST distinfo
 Log Message:
 Update py-mpmath to 0.14.
 per update request from Wen Heping by PR#42755.
 Pkgsrc changes:
 * correct EOL style of installed files
 * Add self-test target
 Released February 5, 2010
 General changes:
 * Fully separated the code into "low-level" and "high-level", permitting the
   use of alternative contexts (the object provides the default
 * 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.
 * Implemented splot() for 3D surface plots (contributed by Jorn Baayen)
 * Permit calling plot functions with custom axes (contributed by Jorn Baayen)
 * 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)
 * 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
 * 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
 * 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
 * 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
 * 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
