* DOC: Add symbol in docstring for classes derived from ABCPolyBasePaul Romano2023-05-106-0/+36
| | | | | 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.

| * BUG: Polynomials now copy properly (#22669)Matteo Raso2022-11-252-1/+6
| | | | | | | | | | | | | | | | On line 502, self.symbol.copy() was called, which causes an AttributeError, since self.symbol is a string, so it doesn't have a copy() method. To fix it, I simply removed the copy() and directly assigned the string.

* DOC: Double backticks in lagfit. (#21948)Matthias Bussonnier2022-07-081-7/+7
| | | | | | Some of the values in the documentation of lagfit are in single-backticks, though single backticks usually means that this is a reference to something else that sphinx tries to resolve. Here I update values that reference nothing to use double backticks (verbatim), or emphasis.
* DOC: Replace the mathematical notation N(...) with text.warren2022-06-261-1/+1
| | | | | | | | | The meaning of the second argument in the mathematical notation N(mu, b) for the normal distribution is not consistent. In some references it is the variance while in others it is the standard deviation. Let's avoid the ambiguity by not using the notation. Fixes #21296

* ENH: Add support for symbol to polynomial package (#16154)Ross Barnowski2022-06-013-42/+368
| | | | | | | Adds a symbol attribute to the polynomials from the np.polynomial package to allow the user to control/modify the symbol used to represent the independent variable for a polynomial expression. This attribute corresponds to the variable attribute of the poly1d class from the old np.lib.polynomial module. Marked as draft for now as it depends on #15666 - all _str* and _repr* methods of ABCPolyBase and derived classes would need to be modified (and tested) to support this change.

* 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

* DOC: Do not leave space between directive name and double colon.Matthias Bussonnier2021-11-033-6/+6
| | | | | | | | | | | From my regular expression foo, those are the only 9 case whereas there are about ~2000 usage that do not have spaces. While this is ok with docutils/sphinx, it does not seem to be documented, and that means that other parsers will see that as comments, leading to for example improper syntax highlighting. This make it also a tiny bit harder to develop alternative rst parsers.

* | 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.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Jarvis2021-06-087-29/+35
| | | | | | | | | | | | | | | | | * 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: Avoid using "set of" when talking about an ordered list.Antony Lee2020-12-291-1/+1
| | | | | | | | | | | | ... or when the input isn't/cannot be a set. I left a few usages, e.g. in random sampling, where "set" is reasonable as informal description of an array as the order doesn't matter; however, for e.g. np.gradient the order of the returned list is clearly important, so "set" is wrong. Also some other minor doc edits noticed during the grepping: using `shape` instead of `form` in `cov` is consistent with most other places; the wording in `Polynomial.trim` now matches other methods on the same class.
* DOC: Update reference to verbatim in a few location.Matthias Bussonnier2020-12-287-7/+7

* DOC: Fix a couple of reference to verbatim and vice versaMatthias Bussonnier2020-12-181-3/+3
| | | | | | | | | | | | | | | | This update a coupe of references (single backticks) that actually are not to verbatim/code (double backticks); and a couple of verbatim to reference when they do actually exists and can be resolved in context. I probably missed other; and stayed simple but spoted a few other inconsistencies that I did not fix: - some ``...`` could actually be :math:`...` but not always clear if it would be better. - some intervals are [``...``], other are ``[...]`` I guess they could be discussed individually; it was mostly the failing references that bothered me.
* TST: Fix crosstalk issues with polynomial str tests.Ross Barnowski2020-12-071-5/+8
| | | | | | | | | | | Polynomial printing tests implicitly depended on calling order, causing the test suite to fail when the test ordering was randomized with the pytest-random plugin (gh-17954). Two factors contributed to this: * Improper setting of class-level test config and * Poorly designed test that overrode an inherited class variable.
