Add missing DEPENDS.
Upstream changes:
1.01
15 Aug 2017
- Move Math::Utils dependancy from 1.06 to 1.10. A test
was failing in 21-secondd.t because the older version's
pl_evaluate() wasn't handling lists back then.
1.00
9 Aug 2017
- Add tests, more POD clean-up, send to CPAN.
18 Jul 2017
- Add references for the central and forward difference
methods.
- Have not been able to find a reference for the second
derivative difference method, annoyingly.
- Minimum perl version set to 5.10.1.
17 Jul 2017
- Added a forward difference approximation method (bug was filed
for this as user Maitraya Baliyan was expecting it instead of
the central difference approximation method that Derivative1()
used).
- Added names forwarddiff() and centraldiff() for export.
Derivative1() is aliased to centraldiff(), so as not to break
old code.
- Likewise, seconddx() is now the exported name of the second
derivative difference method, with Derivative2() aliased to it.
- There is now an EXPORT tag, ':all'.
- POD is more descriptive, has more examples, and uses the
new names.
The makefile.include fragment included by all of the project
makefiles unconditionally sets $(CC), $(LD), $(AR) and $(RANLIB)
to $(PREFIX){gcc,ld,ar,ranlib}. Their intent was to provide a
facility for cross-compiling the code, but the use of $(PREFIX)
for this purpose was unfortunate.
This change adds a patch to set $(PREFIX) to the empty string in
the makefiles, which should fix the problem with the smallest
set of changes.
allow overriding MKOCTFILE_* and use it to provide a full path gfortran,
so the invocation doesn't fail because gfortran isn't normally in PATH
Force the use of bsdtar. unpacking yielding random PaxHeaders.1234 triggers
an octave package sanity check making the build of the 'signal' package
fail with a cryptic error with no further diagnostics.
bump PKGREVISION
Fixes build with PKGSRC_FORTRAN=gfortran (6.4) on netbsd. resulting
binary works fine. I suspect the issue is that the wrong gcc (one without
fortran support) is invoked.
Changes:
- Compat with the new Yahoo iCharts API. Yahoo removed the older API,
this release restores ability to download from Yahoo.
- ``DataReader`` now supports Quandl.
- Removed Oanda as it became subscription only.
- web sessions are closed properly at the end of use
- Handle commas in large price quotes
- Test suite fixes for test_get_options_data
- Test suite fixes for test_wdi_download
- avoid monkey patching requests.Session
- `get_data_yahoo` now treats ``'null'`` strings as missing values
Docs are now generated with pdoc.
Merged Pull Request 24, from @czlee:
* Change to step 4: When it looks for a uncovered zero, rather than starting at row 0, column 0, it starts where it left off, i.e. at the last uncovered zero it found. Since it doesn't start at (0,0), when it gets to the last column it now loops around to the first, and exits unsuccessfully if it got back to where it started. This change reduces this reduces the solving time for (certain) large matrices. For instance, in tests, solving a matrix of size 394×394 goes from about 2 minutes to about 4 seconds.
* Since Python 3 started cracking down on unnatural comparisons, the DISALLOWED constant added in Pull Request 19 no longer works. (It raises a TypeError for unorderable types, as is expected in Python 3.) Since this constant is meant to act like infinity, this modification just changes the two lines where it would otherwise try to make an illegal (in Python 3) comparison between a number and DISALLOWED_OBJ() and gets it to behave as if DISALLOWED is always larger.
Added Travis CI integration.
Added some unit tests. See tests and tests/README.md.
Bug Fixes

Indexing
* Bug in Float64Index causing an empty array instead of None to be returned from .get(np.nan) on a Series whose index did not contain any NaN s
* Bug in MultiIndex.isin causing an error when passing an empty iterable
* Fixed a bug in a slicing DataFrame/Series that have a TimedeltaIndex
I/O
* Bug in read_csv() in which files weren’t opened as binary files by the C engine on Windows, causing EOF characters mid-field, which would fail
* Bug in read_hdf() in which reading a Series saved to an HDF file in ‘fixed’ format fails when an explicit mode='r' argument is supplied
* Bug in DataFrame.to_latex() where bold_rows was wrongly specified to be True by default, whereas in reality row labels remained non-bold whatever parameter provided.
* Fixed an issue with DataFrame.style() where generated element ids were not unique
* Fixed loading a DataFrame with a PeriodIndex, from a format='fixed' HDFStore, in Python 3, that was written in Python 2
Plotting
* Fixed regression that prevented RGB and RGBA tuples from being used as color arguments
* Fixed an issue with DataFrame.plot.scatter() that incorrectly raised a KeyError when categorical data is used for plotting
Reshaping
* PeriodIndex / TimedeltaIndex.join was missing the sort= kwarg
* Bug in joining on a MultiIndex with a category dtype for a level.
* Bug in merge() when merging/joining with multiple categorical columns
Categorical
* Bug in DataFrame.sort_values not respecting the kind parameter with categorical data

scikit-learn is a Python module integrating classic machine learning
algorithms in the tightly-knit scientific Python world (numpy, scipy,
matplotlib). It aims to provide simple and efficient solutions to
learning problems, accessible to everybody and reusable in various
contexts: machine-learning as a versatile tool for science and
engineering.
The package does not include a change log, but one major feature
added since 20140106 is support for transforms of sizes other
than powers of two by means of the chirp Z transform.
* What is new in gsl-2.4:
** migrated documentation to Sphinx software, which has built-in
support for latex equations and figures in HTML output
** add const to declaration of appropriate gsl_rstat routines
** bug fix for #45730: change gsl_sf_sin/cos to libm sin/cos
** fix Cholesky documentation regarding upper triangle on output
** added routines to compute integrals with fixed-point quadrature,
based on IQPACK (Konrad Griessinger)
** added routines for Hermite polynomials, gsl_sf_hermite_*
(Konrad Griessinger)
** added new nonlinear least squares example for fitting
a Gaussian to data
** deprecated routines:
gsl_sf_coupling_6j_INCORRECT
gsl_sf_coupling_6j_INCORRECT_e
** deprecated routine 'gsl_linalg_hessenberg' (replaced
by gsl_linalg_hessenberg_decomp)
** removed routines which were deprecated in v2.1:
gsl_bspline_deriv_alloc
gsl_bspline_deriv_free
** changed COD expression to Q R Z^T instead of Q R Z to
be consistent with standard texts
** added check for nz == 0 in gsl_spmatrix_get
(reported by Manuel Schmitz)
** permit zero-dimension blocks, vectors, matrics, subvectors,
submatrices, and views of the above (bug #49988)
** added routine gsl_linalg_COD_lssolve2 for regularized
least squares problems
some typos.
From DESCR:
Math::Calc::Units is a simple calculator that keeps track of units. It
currently handles combinations of byte sizes and duration only, although
adding any other multiplicative types is easy. Any unknown type is
treated as a unique user type (with some effort to map English plurals
to their singular forms).
being one example), and the logic for building it is conditional, causing
PLIST mismatches for GLIBC users.

Bump PKGREVISION
This package will provide a complete implementation of unicode
maths for XeLaTeX and LuaLaTeX. Unicode maths is currently
supported by the following fonts: Cambria Math (Microsoft),
Minion Math (Johannes Kuster, typoma GmbH) Latin Modern Math
(Boguslaw Jackowski, Janusz M. Nowacki) TeX Gyre Pagella Math
(Boguslaw Jackowski, Janusz M. Nowacki) Asana-Math fonts
(Apostolos Syropolous), Neo Euler (Khaled Hosny), STIX (STI
Pub), and XITS Math (Khaled Hosny). As well as running XeTeX or
LuaTeX, this package requires recent versions of the fontspec,
expl3, xpackages, filehook, ucharcat and lualatex-math
packages.
The mathspec package provides an interface to typeset
mathematics in XeLaTeX with arbitrary text fonts using fontspec
as a backend. The package is under development and later
versions might to be incompatible with this version, as this
version is incompatible with earlier versions. The package
requires at least version 0.9995 of XeTeX.
Highlights
* Operations like a + b + c will reuse temporaries on some platforms,
resulting in less memory use and faster execution.
* Inplace operations check if inputs overlap outputs and create temporaries
to avoid problems.
* New __array_ufunc__ attribute provides improved ability for classes to
override default ufunc behavior.
* New np.block function for creating blocked arrays.
New functions
* New np.positive ufunc.
* New np.divmod ufunc provides more efficient divmod.
* New np.isnat ufunc tests for NaT special values.
* New np.heaviside ufunc computes the Heaviside function.
* New np.isin function, improves on in1d.
* New np.block function for creating blocked arrays.
* New PyArray_MapIterArrayCopyIfOverlap added to NumPy C-API.
This is a minor bug-fix release in the 0.20.x series and includes some small regression fixes, bug fixes and performance improvements. We recommend that all users upgrade to this version.
