BUG: Polynomials now copy properly (#22669)

2022-11-25T05:28:35+00:00

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.

ENH: Add support for symbol to polynomial package (#16154)

2022-06-01T22:02:43+00:00

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.

TST: increase error tol from 12 to 11 decimal places for test_approximation

2021-08-24T15:54:52+00:00

SVML library is accurate upto 4ULP and hence reduces the accuracy
slightly

TST: Branch coverage improvement for `np.polynomial` (#18499)

2021-02-28T08:58:54+00:00

* added tests for vander_nd in test_polyutils to cover some of the missed branches

* added tests to polyline and vander to improve branch coverage

* added tests to test_legendre.py to improve branch coverage

TST: Fix crosstalk issues with polynomial str tests.

2020-12-07T23:39:54+00:00

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.

ENH: Improved `__str__` for polynomials

Handle TypeError in _generate_str for coefs.

2020-05-13T22:01:36+00:00

Add a fallback for TypeErrors that are raised when attempting
to compare arbitrary elements (e.g. strings or Python complex)
to 0 in _generate_str.
