* DOC: Add symbol in docstring for classes derived from ABCPolyBasePaul Romano2023-05-101-0/+6
| | | | | A 'symbol' argument was added in ABCPolyBase in 1.24 and documented there, but the docstrings for derived classes (e.g., Polynomial) were not updated.
* DOC: fix code sample for leg2poly (#21253)Pax2022-03-261-1/+1
| | | | | | | The previous code sample throws an attribute error around `P.leg2poly()`. Since commit d41fc4d (2012), leg2poly is not exposed in np.polynomial, and need to be explicitly called from `legendre`. Fixes #20925

* duplicate item in see also.Matthias Bussonnier2021-09-221-1/+1
| | | | | | | | Ok, I know legmul is important, I'm not sure I need it twice. Joking aside, I belive that's a wrong copy-past, as other functions have `legmulx, legmul`, but as this is the docs of legmulx, I guess the author removed the `x` without realising legmul was already present.
* DOC: fix formatting of a return value of polynomial fit methodsSamyak S Sarnayak2021-09-211-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes #19897 The 2nd return value of the following methods/functions were badly formatted and the list was all appearing in a single line. Changed them to separate points which are rendered nicely. - numpy.polyfit - numpy.ma.polyfit - numpy.polynomial.polynomial.polyfit - numpy.polynomial.polynomial.Polynomial.fit - numpy.polynomial.chebyshev.chebfit - numpy.polynomial.chebyshev.Chebyshev.fit - numpy.polynomial.hermite.hermfit - numpy.polynomial.hermite.Hermite.fit - numpy.polynomial.hermite_e.hermefit - numpy.polynomial.hermite_e.HermiteE.fit - numpy.polynomial.laguerre.lagfit - numpy.polynomial.laguerre.Laguerre.fit - numpy.polynomial.legendre.legfit - numpy.polynomial.legendre.Legendre.fit Also fixed erroneous links to `numpy.full` which were actually referring to the `full` argument. Changed those to code strings (double backticks) from single backticks. Also fixed formatting issues in the 3rd return value of numpy.polyfit (and hence also numpy.ma.polyfit).
* DOC: Adjust polyfit doc to clarify the meaning of w (#18421)Mike Jarvis2021-06-081-4/+5
| | | | | | | | | | | | | | | | | * DOC: Adjust polyfit doc to clarify the meaning of w cov='unscaled', in particular, had inconsistently referred to a weight of 1/sigma**2, while the doc for w says it should be equal to 1/sigma. This change clarifies w to comport with more typical meanings of weights in weighted least squares, and makes clear that cov='unscaled' is appropriate when the weight w**2 = 1/sigma**2. See Issue #5261 for more discussion of the errors/confusion in the previous doc string. * Update doc text for w in all polynomial module fit functions Co-authored-by: Stefan van der Walt <sjvdwalt@gmail.com> Co-authored-by: Ross Barnowski <rossbar@berkeley.edu>
* DOC: cleanup of numpy/polynomial.Matthias Bussonnier2021-01-281-6/+0
| | | | | Numpydoc format says that the colon need o be omitted if there is no type, there were also some empty Examples Sections
* 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: Add missing bracket (gh-16051)Chunlin2020-04-251-2/+2

* 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.
* MAINT: polynomial: Add an N-d vander implementation used under the hood of ↵Eric Wieser2019-09-141-2/+2
| | | | | | | | 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 Wieser2019-03-161-18/+1
| | | | | | 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 Wieser2019-03-121-20/+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: 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 Reddy2018-12-141-20/+21
| | | | | | | | * 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 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 Harris2016-12-141-1/+1
| | | | | | | 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 Harris2016-01-191-21/+16
| | | | | | | * 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 legfitJonathan Underwood2016-01-181-8/+39
| | | | | | | | | | 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.
