* TST: Replace yield tests in polynomial/tests/test_classes.Charles Harris2018-04-081-65/+49

* MAINT: Remove all uses of run_module_suite.Charles Harris2018-04-069-46/+2
| | | | | That function is nose specific and has not worked since `__init__` files were added to the tests directories.
* TST: Update modules `test` to PytestTester.Charles Harris2018-04-041-2/+3
| | | | | | | | Numpy can now be tested using the standard `python -c"import numpy; numpy.test()"` construct.
* MAINT: Remove "bench" from testing modules `__init__`s.Charles Harris2018-03-311-1/+0
| | | | | The "bench" testing with the old bench files is no longer supported. These days we use `runtests.py` and `asv`.
* MAINT: Do not use random when testing roots.Charles Harris2018-02-161-3/+3
| | | | | | | | | | | The `check_roots` function in numpy/polynomial/tests/test_classes.py was using random numbers without a seed to generate the random roots to be checked. This made the test sensitive to the random state, with the result that currently two of the roots are close together and fail the test to the default seven digit precision when running on the Mac. The failure is probably due to a combination of library and compiler differences between the Mac and the other platforms tested.. The fix here is to hardwire the test values rather than use random numbers.

* TST: Add tests for `lbnd` and `scl` in polynomial integration.Charles Harris2017-10-266-0/+18
| | | | | | The `lbnd` and `scl` parameters of the various polynomial integration functions are documented to be scalars. Add tests that those parameters are checked and ValueError raised when it is not so.
* MAINT: Add parameter checks to polynomial integration functions.Charles Harris2017-10-266-6/+31
| | | | | | | It was not being checked that the `lbnd` and `scl` parameters were scalars as required. Closes #9901.

|\ | | | | TST, MAINT: Add `__init__.py` files to tests directories.
| * TST, MAINT: Add `__init__.py` files to tests directories.Charles Harris2017-08-061-0/+0
| | | | | | | | | | | | | | | | This allows pytest to run with duplicate test file names. Note that `python <path-to-test-file>` no longer works with this change, nor will a simple `pytest numpy`, because numpy is imported from the numpy repository. However, `python runtests.py` and `>>> numpy.test()` are still available.
* | MAINT: Use moveaxis instead of rollaxis internally (#9475)Nico Schlömer2017-08-106-30/+30
| | | | | | | | | | Also add a hint to the documentation advising the use of moveaxis over rollaxis. Tests for rollaxis are left alone.

* MAINT: Rename chebinterp to chebinterpolation and add test.Charles Harris2017-07-293-43/+126
| | | | | | | * 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 Mericle2017-07-242-1/+79
| | | | | | | | | 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.
* TST: Remove unittest dependencies in numpy/polynomial/tests.Charles Harris2017-07-248-78/+85

* MAINT: Rearrange files in numpy/testing module.Charles Harris2017-07-041-1/+1
| | | | | | | | | | | | | | | | | The aim here is to separate out the nose dependent files prior to adding pytest support. This could be done by adding new files to the general numpy/testing directory, but I felt that it was to have the relevant files separated out as it makes it easier to completely remove nose dependencies when needed. Many places were accessing submodules in numpy/testing directly, and in some cases incorrectly. That presented a backwards compatibility problem. The solution adapted here is to have "dummy" files whose contents will depend on whether of not pytest is active. That way the module looks the same as before from the outside. In the case of numpy itself, direct accesses have been fixed. Having proper `__all__` lists in the submodules helped in that.

* ENH: Use `__array_ufunc__ = None` in polynomial convenience classes.Charles Harris2017-04-272-2/+10
| | | | | | | | Add `__array_ufunc__ = None` to ABCPolyBase. This ensures that polynomial convenience classes will not participate in ufuncs and will have priority when combined with an ndarray in a Python binary operator. `__array_priority__` is removed, as it is no longer needed.
* MAINT: Use normalize_axis_index in all python axis checkingEric Wieser2017-02-206-48/+18
| | | | | | | 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

* DEP: Fix escaped string characters deprecated in Python 3.6.Charles Harris2016-12-146-21/+21
| | | | | | | 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 and small fixes to polyvalfromroots.Charles Harris2016-06-122-19/+25
| | | | | | | | | Simplify the logic a bit and make behavior consistent with polyval. Note that this adds a check that the number of dimensions of the array of the evaluation points is less than the number of dimensions of the array of roots when tensor=False. That check is missing from polyval and needs to be added.
* ENH: Add `polyrootval` to numpy.polynomiale-q2016-06-122-2/+149
| | | | | | | | | | | As one can easily encounter when working with high-order signal processing filters, converting a high-order polynomial from its roots to its polynomial coefficients can be quite lossy, leading to inaccuracies in the filter's properties. This PR adds a new function, `polyrootval` - based on `polyval` - that evaluates a polynomial given a list of its roots. The benefit of calculating it this way can be seen at scipy/scipy:6059. Some tests are included, as well.
