* DOC: Update reference to verbatim in a few location.Matthias Bussonnier2020-12-281-1/+1
| | | | | Single backticks default role is reference, while here it seem to be for verbatim. Fix it in a couple of places.

* MAINT: Remove nickname from polynomial classes. (gh-16589)Ross Barnowski2020-07-081-1/+0
| | | | | | | | | | | | | | | | * MAINT: Remove nickname from polynomial classes. The convenience classes derived from ABCPolyBase had a nickname attribute that was only used internally in the previous implementation of __str__. After the overhaul of __str__ in #15666, this attr is no longer used. * DOC: Add release note. Add release note to notify users of removal of the abstract property, and highlight users that may be affected by the change. * DOC: fixed rST in release note
* DOC: Fixes for 18 broken links (#16472)bjnath2020-06-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * DOC: Fixes for 18 broken links This, with PR #16465, should fix nearly all the remaining broken links on the site. 4 or 5 others should be easy to fix and just need attention from someone more knowledgeable -- will open an issue. For release notes with dead links, I could usually find links on archive.org for roughly contemporary versions. * DOC: Update to "Fixes for 18 broken links #16472" * Obsolete links, previously commented out, now deleted: https://github.com/numpy/numpy/pull/16472#discussion_r433928958 * Semantic markup for reference to Python class: https://github.com/numpy/numpy/pull/16472#discussion_r433553928 * Missing :ref: in internal link: https://github.com/numpy/numpy/pull/16472#discussion_r433554484 Not included: Resolution on using external/internal doc link in .py: https://github.com/numpy/numpy/pull/16472#discussion_r433554824 * DOC: Add internal link for 'Fixes for 18 broken links' PR #16472 Making reference [1] an internal link in function_base.py => numpy.vectorize.html * DOC: Redirect 2 link fixes in PR #16472 * governance.rst link reverted * ununcs.rst `overridden` link goes where it was meant to per https://github.com/numpy/numpy/pull/16472#pullrequestreview-424666070

* MAINT: Remove unnecessary 'from __future__ import ...' statementsJon Dufresne2020-01-031-2/+0
| | | | | As numpy is Python 3 only, these import statements are now unnecessary and don't alter runtime behavior.

| | | | | | | | the vander2d and vander3d functions The generalization is not exposed in the public API yet, but it could be if the need arises. The shape / dtype conversion logic is left as is for now, even if it might be broken.

* MAINT: Unify polynomial power functionsEric Wieser2019-03-161-0/+3
| | | | | | These power functions are all the same - the algorithm used does not care about the basis. `polypow` and `chebpow` have some optimizations in their versions, which this maintains
* DEP: polynomial: Be stricter about integral argumentsEric Wieser2019-03-161-18/+8
| | | | | | | | | | | | | | | | | | | This changes the behavior for: * The `deg` and `axis` arguments of `<type>der` * The `deg` and `axis` arguments of `<type>int` * The `deg` argument of `<type>gauss` * The `deg` argument of `<type>vander2d` * The `deg` argument of `<type>vander3d` The old behavior was: * Raise `ValueError` if the argument is a float, but not an integral one * Allow a float like `1.0` to mean `1`. This is inconsistent with most other integer-accepting APIs in numpy, which require these to be actual integers, and raise TypeError when they are not. The new behavior is: * Raise `TypeError` if the argument is a float, but not an integral one * Emit a `DeprecationWarning` if a float like `1.0` is passed, continuing to allow it its old meaning.
* MAINT: Unify polynomial fitting functionsEric Wieser2019-03-151-75/+1
| | | | | | | | | | These fitting functions are all the same - the algorithm used does not care about the basis. This was done using: * A regex find / replace on all but poly and cheb * A manual diff showing that cheb differed only by whitespace * A manual diff showing that poly differed in `deg.ndim == 1` vs `deg.ndim > 0`. Given that this function only allows `deg.ndim <= 1`, and `ndim >= 0`, these two comparison are equivalent.
* MAINT: Unify polynomial addition and subtraction functionsEric Wieser2019-03-141-19/+2
| | | | These functions are all the same - the algorithm used does not care about the basis.
* MAINT: Unify polynomial division functionsEric Wieser2019-03-121-0/+1
| | | | | | These division functions are all the same - the algorithm used does not care about the basis. Note that while chebdiv and polydiv could be implemented in terms of this function, their current implementations are more optimal and exploit the properties of a multiplication by a basis polynomial.
* MAINT: Adjust variable names for consistencyEric Wieser2019-03-121-9/+9
| | | | | This makes the variable names in polydiv and chebdiv match polyutils._div. It also brings the order of the special-casing in line to match.
* MAINT: Unify polynomial valnd functionsEric Wieser2019-03-121-24/+4
| | | | No point writing the same function 12 times, when you can write it once
* MAINT: Move duplicate implementations of ABCPolyBase._fromroots into polyutilsEric Wieser2019-03-111-15/+1
| | | | | | Every implementation is the same right now, other than calling different line / mul functions. Found by LGTM.
* MAINT: Merge duplicate implementations of `*vander2d` and `*vander3d` functionsEric Wieser2019-03-021-23/+2
| | | | | | | Every implementation is the same right now, other than calling a different `*vander` function. Merging these into a single private function taking a callback results in significant deduplication. Found by LGTM.
* TST, DOC: enable refguide_checkTyler Reddy2018-12-141-19/+19
| | | | | | | | * ported the refguide_check module from SciPy for usage in NumPy docstring execution/ verification; added the refguide_check run to Azure Mac OS CI * adjusted NumPy docstrings such that refguide_check passes

| * ENH: Add support for ipython latex printing to polynomialEric Wieser2018-08-121-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Choices made, and the alternatives rejected (for no particularly strong reason): 1. Show terms in ascending order, to match their internal representation * alternative: descending, to match convention 2. Shows 0 terms in gray * alternative: omit entirely * alternative: show normally to aid comparison 3. Write each term as `basis(ax + b) * alternative: write as `basis(u) ... where u = ax + b` * alternative: show the normalized polynomial In future it would perhaps make sense to expose these options to the end user

* MAINT: Add parameter checks to polynomial integration functions.Charles Harris2017-10-261-1/+5
| | | | | | | It was not being checked that the `lbnd` and `scl` parameters were scalars as required. Closes #9901.

* MAINT: Use moveaxis instead of rollaxis internally (#9475)Nico Schlömer2017-08-101-5/+5
| | | | | Also add a hint to the documentation advising the use of moveaxis over rollaxis. Tests for rollaxis are left alone.
* ENH: Show domain and window as kwargs in reprEric Wieser2017-08-101-2/+2

* MAINT: Rename chebinterp to chebinterpolation and add test.Charles Harris2017-07-291-32/+85
| | | | | | | * Rename chebinterp to chebinterpolation as suggested. * Make some fixes to the Chebyshev class function. * Refactor TestInterpolation. * Add test for the Chebyshev.interpolation class function.
* ENH: Add np.polynomial.chebyshev.chebinterp functionLukas Mericle2017-07-241-1/+59
| | | | | | | | | The chebinterp function interpolates a function at the Chebyshev points of the first kind using a Chebyshev series. The resulting interpolation approximates a polynomial fit minimizing the L_inf norm. This function is useful e.g. for estimating roots before running a root-finding function.
* BUG: KeyboardInterrupt is swallowed all over the placeEric Wieser2017-06-031-2/+2
| | | | Bare except is very rarely the right thing
* MAINT: Use normalize_axis_index in all python axis checkingEric Wieser2017-02-201-8/+3
| | | | | | | As a result, some exceptions change from ValueError to IndexError This also changes the exception types raised in places where normalize_axis_index is not quite appropriate
* Applied same fix as 1695458be to remaining 5 polynomial typesTom Boyd2017-02-011-1/+1
| | | | | | - Fixes documentation of polynomial types `*vander2d()` methods to give the correct last index of the pseudo-Vandermonde matrix returned expressed in terms of x and y.

* DEP: Fix escaped string characters deprecated in Python 3.6.Charles Harris2016-12-141-5/+5
| | | | | | | In Python 3.6 a number of escape sequences that were previously accepted -- for instance "\(" that was translated to "\\(" -- are deprecated. To retain the previous behavior either raw strings must be used or the backslash must be properly escaped itself.

* MAINT: Refactor polynomial leastsquares fits.Charles Harris2016-01-191-23/+18
| | | | | | | * Rewrite the documentation for `deg`. * Check that the passed degrees are int and raise if not. * Do not accept `deg` arguments that do not convert as 0-D or 1-D. * Sort passed degree terms for repeatability.
* ENH: Allow specification of terms to fit in chebfitJonathan Underwood2016-01-181-5/+34
| | | | | | | | | | The argument `deg` is enhanced to allow an array_like argument to past which specifies which terms to include in the fit. The returned coef array is exapnded to have entries of 0 for all coefficients which were not included in the fit.
